Victorian debutant Scott Boland produced the spell of a lifetime as Australia secured an Ashes series victory with an emphatic triumph over England in the third Test at the MCG on Tuesday.

England were skittled for a feeble 68 as Australia clinched an unassailable 3-0 series lead with victory by an innings and 14 runs inside two days and one session.

Player of the Match Boland was the story of the third day, claiming four wickets in 11 deliveries including England skipper Joe Root to finish with remarkable second-innings figures of 7-6 from four overs.

Root offered the only resistance with 28, after the visitors resumed at 31-4 but wilted against a hungry Australian attack.

Mitchell Starc (29-3) got the first breakthrough of Ben Stokes bowled for 11, before Boland took over as England lost their final five wickets for eight runs.

Boland first trapped Jonny Bairstow lbw for 5, despite a review, after he was dropped at gully by Cameron Green.

The debutant proceeded to claim the key wicket of Root caught by David Warner at first slip, before dismissing Mark Wood and Ollie Robinson for ducks.

Green claimed the final wicket to secure the series victory, clean bowling Jimmy Anderson to bowl England out for 68, their ninth lowest total in Ashes history.

England lasted only 15.4 overs on the third day, with the game being the shortest completed Test match hosted by Australia in 70 years, lasting 1084 balls.

The all-clear was given for day three of the Boxing Day Ashes Test to start on time after Australia and England players all tested negative for coronavirus.

There had been a scare ahead of the second day of the third Test in Melbourne when a member of the tourists' family group returned a positive COVID-19 result.

The England players and management were forced to remain at their hotel while they awaited their test results, before being given the green light to travel to the ground, with play starting half an hour later than scheduled.

Both sets of players took PCR tests after the second day of play and Cricket Australia on Tuesday confirmed all tested negative, meaning there were no delays for the third day.

The England team's support staff and the family members who tested positive on Monday – reportedly six people in total – are in isolation.

Australia were well on course to retain the urn after reducing Joe Root's side to 31-4 in their second innings after two days of play, with England trailing by 51 runs and 2-0 down in the series.

Marcus Harris said "it's about trusting what I do" after going some way to silencing his doubters on day two of the third Ashes Test against England.

The opening batsman went into the contest at the MCG with a best effort of 23 from four innings, but top scored with 76 – the only Australian to make more than 40 in the first innings.

It proved a particularly good knock in the context of a day that saw Australia restricted to 267 having bowled England out for 185 on day one, before dominating the final hour to have the tourists 31-4 and still 51 runs in arrears.

Harris was thrilled to play his part on his home ground and prove a few people wrong in the process.

"It was good to spend a bit of time in the middle today. I had a bit of a battle in the first couple of Tests but it was good to be home and play on a familiar wicket," he told ABC Radio.

"There's a lot of media around but the support I've had from within and my close circle of people has been unbelievable. It's about trusting what I do."

James Anderson had starred with the ball for England, taking 4-33 to give the visitors an opportunity to get back into the game.

But Mitchell Starc (2-11) and Scott Boland (2-1) combined to have Zak Crawley (5), Dawid Malan (0), Haseeb Hameed (7) and nightwatchman Jack Leach (0) dismissed in a devastating final hour, much to the delight of the Melbourne crowd.

Harris added: "The way the wicket is, the amount of grass, there's always something in it for the bowlers.

"Jimmy Anderson bowled unbelievably, as did our bowlers in the end."

James Anderson rued England's disappointing final hour after the tourists had worked hard to fight their way back into the third Ashes Test against Australia on day two.

Having been bowled on for 185, England's star paceman Anderson led the way with 4-33 to restrict Australia to 267 all out and a first-innings lead of 82 at the MCG.

But a woeful last hour amid familiar failings with the bat saw England close on 31-4, still trailing by 51 runs as Australia moved ever closer to sealing the series.

"It's obviously a disappointing finish to the day, I thought we bowled well through the day to keep the pressure on Australia," England's all-time leading wicket taker Anderson told BT Sport.

"It wasn't easy to bowl them out for less than 300 on that wicket but it was a good effort to do so.

"It was a difficult 12 overs, good spell from Mitchell Starc and Pat Cummins, they're world-class bowlers so you expect that. It was disappointing to lose four wickets in those 12 overs."

England looked set to enjoy their best day of a poor series so far until Starc (2-11) and home favourite Scott Boland (2-1) combined to have Zak Crawley (5), Dawid Malan (0), Haseeb Hameed (7) and nightwatchman Jack Leach (0) dismissed, much to the delight of the Melbourne crowd.

Anderson, though, insists there is plenty of unity within England's camp.

"It's been a frustrating tour so far full stop. We are working hard and trying to put things right and trying to put in better performances," he added.

"I thought we did that with the ball, we hit our areas with the ball but it was a frustrating end to the day.

"We are together as a group. We have a really good group of guys. We know how hard the batters are working and as bowlers we are doing the same. 

"The cohesion is definitely there it's just frustrating we are not putting the two things together at the same time."

Australia took four late wickets amid a devastating spell with the ball to grab a stronghold on their way to sealing the Ashes after England had fought back on day two of the third Test at the MCG.

Mitchell Starc claimed the scalps of Zak Crawley and Dawid Malan in successive balls before Victorian debutant Scott Boland had Haseeb Hameed caught behind and bowled Jack Leach to leave the visitors reeling.

England were 31-4 at stumps, trailing by 51 runs as Australia, who lead the series 2-0, look to clinch the Ashes in Melbourne. Joe Root (12*) and Ben Stokes (2*) will resume at the crease on day three.

The visitors had rallied to keep the Boxing Day Test alive, having dismissed Australia for 267 led by veteran James Anderson with 4-33.

All this after drama forced the resumption of play to be delayed after a coronavirus scare within the England camp, before all the players were cleared for an 11am local start.

Australia had resumed at 61-1 after England were all out for 185 on the first day. Marcus Harris resumed at the crease and top scored with 76 on his home deck.

England had made good inroads into the Australia batting order at 110-4, dismissing number one Test batsman Marnus Labuschagne for 1 and vice-captain Steve Smith for 16 from Chris Wood (71-2) and Anderson respectively.

Harris was the only Australian to score more than 40, with Travis Head (27) getting a start before falling to Ollie Robinson (64-2), who had a hamstring scare but played on.

England appeared set for a nominal first-innings deficit before a late cameo from Starc (24*) and captain Pat Cummins (21) opened up an 82-run lead.

However, Australia turned the game in a stunning final 45 minutes with Cummins almost having Crawley caught behind for a duck when Alex Carey botched a chance, before the English opener went in the next over to Starc (11-2).

Starc trapped Malan lbw next ball despite a review, before Boland was introduced to the attack, having Hameed caught by Carey before clean bowling Leach two balls later.

Starc misses rare Boxing Day hat-trick

Starc almost claimed the first Boxing Day Test Ashes hat-trick since Shane Warne in 1994 when he dismissed Crawley and Malan in successive deliveries. England skipper Root survived a close call on the hat-trick ball which had the MCG crowd on their feet as it whizzed past the bat.

Local hero fires up crowd

Local debutant Boland only managed one wicket in the first innings but received great support from his home crowd during his brief batting innings before a double strike with his only over after being thrown the ball late in the day.

England suffered a coronavirus scare ahead of day two of the third Ashes Test against Australia at the MCG.

The players and management were forced to remain at their hotel after a positive COVID-19 test was recorded within the team's family group.

Players and staff had to await the results of their own coronavirus tests before eventually being given the all-clear to head to the stadium.

England, who trail the series 2-0, were bowled out for 185 on day one after Australia won the toss and put the tourists in.

Australia will resume on 61-1 after James Anderson accounted for David Warner (38) before the close of play on day one.

Pat Cummins need only to avoid defeat in Melbourne to retain the Ashes after one-sided victories in Brisbane and Adelaide.

England have made sweeping changes ahead of the Ashes Boxing Day Test with Rory Burns, Ollie Pope, Stuart Broad and Chris Woakes all omitted.

Batsmen Zac Crawley and Jonny Bairstow earn their first opportunities during this Ashes series while paceman Mark Wood and spinner Jack Leach have been recalled.

England trail 2-0 in the Ashes after heavy defeats in Brisbane and Adelaide and will look to keep the series alive at the MCG starting on Sunday.

Opening batsman Burns has been left out after managing only 51 runs at 12.75 along with Ollie Pope with 48 runs at 12 in the first two Tests.

Broad and Woakes make way as England look to add variety to their attack which has allowed Australia to score more than 400 runs in the first innings of both Test matches.

England vice-captain Jos Buttler told reporters on Saturday: "I'd say the reaction is just an honest one from the group. We've had some honest conversations.

"When you come and play Australia we need to be at your best. We're honest with ourselves that we haven’t been there yet. We have to find that very quickly."

Victorian fast bowler Scott Boland has been confirmed for a shock debut in the Ashes Boxing Day Test at the MCG.

Australia captain Pat Cummins, who also returns to the XI after his COVID-19 scare in Adelaide, confirmed the decision on Christmas Day, with Jhye Richardson and Michael Neser dropping out due to soreness.

Boland, who plays his state cricket for Victoria at the MCG, took 8-89 in a match last month against New South Wales. The 32-year-old right-arm fast bowler has played 14 ODIs and three T20Is for Australia and has taken 91 wickets at 25.71 in 26 first-class games at the MCG.

"Really excited for Scott debuting here on his home ground," Cummins told reporters. "Jhye and Ness pulled up a little bit sore after Adelaide, so we made the decision to bring in Scotty. It's a luxury to have someone like him ready to go. He's fresh.

"We earmarked him as a chance for here and the SCG. We think he's really well suited. His record speaks for itself here in domestic cricket. Home ground and having someone fresh and ready to go were big factors."

Cummins explained that Richardson, who took a second-innings five-wicket haul to earn Australia victory in the second Ashes Test and a 2-0 series lead, was carrying a minor leg injury.

"He's pretty sore," he said. "We were umming and ahing. He had a bit of bowl-out yesterday.

"We felt seven days off, give him enough rest. He's got a small leg injury which is nothing major but we felt rather than risk a longer term injury, give him a week off."

Josh Hazlewood remains unavailable due to a side injury but is in the mix to return for the fourth Ashes Test in Sydney starting January 5.

Joe Root says the England captaincy is "not a dictatorship" as the tourists prepare to try and keep the Ashes series alive in the Boxing Day Test at the MCG.

Root called on his attack to be "braver" by bowling fuller lengths after Australia went 2-0 up with a resounding 275-run victory at the Adelaide Oval.

England start the third Test in Melbourne knowing they must win to have any chance of regaining the urn and captain Root does not see a problem with himself and the bowlers having a difference of opinion.

"I like to give our bowlers, especially the senior ones, that responsibility," Root said. "They [James Anderson and Stuart Broad] have more than 300 Tests between them and over 1,000 wickets, and they know what they are doing.

"It's working alongside them, it's not a dictatorship. Every now and again, you don't always agree on everything and that's fine.

"Ultimately, it's about coming to a point where you get the results we want. Unfortunately, in the last game, we didn't quite get there."

Root will break former Pakistan batter Mohammad Yousuf's record of 1,788 Test runs in a calendar year if he scores 159 or more in England's last match of 2021.

England must raise their game in the field, having dropped at least five catches in four of their past five Tests. They put seven chances down in Adelaide.

Australia have lost two of the previous three Boxing Day Tests, both of those defeats coming at the hands of India.

England set to ring the changes

The tourists are set to wield the axe after two heavy defeats, with Zak Crawley, Jonny Bairstow, Jack Leach and Mark Wood potentially getting the nod.

Rory Burns is reportedly in danger of being dropped and fellow opener Haseeb Hameed is also under pressure, while Chris Woakes looks likely to miss out after he went for 149 runs and took only one wicket in the second Test.

Ollie Pope has also been out of sorts early in the series, failing to reach double figures in his past three innings after starting with 35 at the Gabba.

Crawley has not played for England since a drawn Test against India at Trent Bridge in August.

Cummins returns, Labuschagne on top of the world

Pat Cummins returns to skipper Australia after missing the last Test due to coming into close contact with a positive coronavirus case at a restaurant in Adelaide.

Australia now have the number one Test bowler in the world in Cummins and the best batter on the planet, with Marnus Labuschagne taking that mantle from Root.

Labuschagne is the leading run-scorer in the series with 228 at an average of 76 following his maiden Ashes century in the second Test.

Josh Hazlewood is set to miss out again due to a side injury, so Jhye Richardson should get another opportunity after claiming a maiden five-wicket Test haul on his Ashes debut last week.

Australia are set to be without Josh Hazlewood for the Boxing Day Test at the MCG after sitting out of training on Friday as he continues to recover from a side strain.

The 30-year-old fast bowler, who has taken 215 wickets in 56 Test matches, missed the second Ashes Test after sustaining the injury during the series opener in Brisbane.

Hazlewood did not partake in Australia's nets session on Friday, instead watching on as Jhye Richardson and Michael Neser jousted for his spot for the third Test.

Australian allrounder Cameron Green said that Hazlewood would likely be ready for the fourth Ashes Test in Sydney starting on January 5.

“He's going really well,” Green told reporters about Hazlewood. “He was doing his run-throughs today and he’s looking really good. I haven't spoken to the guys for this game, but definitely lock him in for Sydney.”

Neser looms as the bowler likely to drop out for returning captain Pat Cummins after taking one wicket in each innings in Adelaide, with Richardson likely to hold his spot after a second-innings five-wicket haul.

"I spoke to him today and he is good to go," Green said about his state teammate Richardson. "He was so pumped after how he went in that second innings, as you would be, and he’s ready to go again."

Joe Root has backed himself to score a maiden Test century in Australia as England search for a response in the Ashes after a dismal start.

England have been comfortably dispatched by Australia in the opening two Tests, succumbing to a 275-run defeat in Adelaide after a nine-wicket beating in Brisbane.

The tourists are without a win in 12 Test matches in Australia – their joint-longest such run (also 12 between January 1937 to February 1951) – and must defeat Justin Langer's side in Melbourne to stop them from retaining the urn.

Root has been in fine form, scoring 175 runs at an average of 43.75, but the England captain has yet to convert to three figures despite registering eight half-centuries in Australia - only Bruce Laird (nine times) has reached fifty more times in Tests Down Under without ever managing to a ton.

Indeed, Root has already surpassed Michael Vaughan (1,481 in 2002) for the most Test runs in a calendar year by an England player and sits fourth on the all-time list with 1,630 runs in 2021.

Root will eye the Boxing Day Test as a chance to further his record haul and the 30-year-old remains confident he can manage a maiden ton on Australian soil sooner rather than later.

"I expect a response from our players and I would like to bring a nice Christmas present home for everyone who stays up," Root told reporters.

"I feel in a really good place with my batting. I feel confident I can, in these next three games, bang out a hundred in these conditions.

"I know that's a brave thing to say but my conversion rate, this year, it's not been an issue at all.

"I feel like I have managed that well and have an understanding of how I want to score my runs. There's clarity there, I just need to keep putting myself in those positions, just have the bit between my teeth, [make it] 'over my dead body'".

Australia number three Marnus Labuschagne, who leads the Ashes scoring charts with 228 runs, overtook Root as the ICC's top-ranked men's Test batter and England's skipper admitted he wants his title back.

"I've never been one for that but it would be nice to have it back for Christmas," he responded when asked about being displaced at the top of the rankings.

Root will also be expecting a response from his bowling attack after he provided a scathing summary post-match in the second Test, in which he slammed his bowlers for repeating mistakes from four years ago and needing to be braver with their lengths.

He hopes his outburst, which was followed up by a "brutally honest" Chris Silverwood debrief with the England players, will act as a catalyst for change on Saturday.

"I did [get angry] at the end of the last game because of the situation we're in and the manner in which we lost," he continued.

"I'll always try to look at things with a level, pragmatic approach but I don't think you could after the way we've played those last two games. I expect a response from everyone this week.

"Twice now we've got ourselves into a position, second innings in Brisbane, first innings in Adelaide, with decent partnerships between me and Mala [Dawid Malan], we needed to go on and we didn't.

"Sometimes that can happen, but the first 20 balls, starting your innings, you've got to be disciplined, you've got to know how you're going to get yourself in the game and we can't afford to be losing eight wickets for 70 or 80 runs.

"It is not good enough, it is not the level that an England Test team should be playing at. The guys know that and they're very aware of that. Their work ethic is very good and you'll have seen how guys practiced and how long they bat for in the nets, but sometimes I think we can be smarter about what we are practicing and how we are practicing.

"And understanding that batting, in my opinion, it's about making good decisions for long periods of time."

Australia head coach Justin Langer backed Mitchell Starc to be fit for the Boxing Day Test, though it remains unclear whether Josh Hazlewood will feature.

Langer's side boast a 2-0 series lead after a nine-wicket demolition of Joe Root's tourists in the opening Test in Brisbane, in which Starc bowled opener Rory Burns with the first delivery of the Ashes, and a 275-run victory in Adelaide.

Starc managed match figures of 6-80 at the Adelaide Oval as Australia made it nine wins in day-night Test matches, the only side with a perfect 100 per cent winning record, in the absence of Pat Cummins and Hazlewood, who injured himself at the Gabba.

Cummins is expected to return in Melbourne after coming into close contact with a positive COVID-19 case last Wednesday, but Langer remained unsure on Hazlewood's fitness as he praised the work of left-armer Starc.

On Starc, Langer told reporters: "He should be fine. He's tough. If he's not right, then we'll look at it. But at this stage, there's no indication suggesting he won't be playing the next Test.

"I'd be very surprised if he doesn't get up for Boxing Day. We will wait and see how Hazlewood pulls up.

"I honestly thought Starc was almost the man of the match last game. He became the leader of the group.

"There's been a lot of talk about Mitch Starc for the last few years but he just keeps turning up. He's an unbelievable athlete and he's incredibly fit.

"His resilience to just keep coming up over and over and over again is remarkable really, and his consistency of length and the way he controlled the tempo of the game last game was a great credit to him, particularly with Patty (Cummins) and Hazlewood not playing."

Indeed, Starc has been the pick of fast bowlers in the series thus far, picking up nine wickets at an average of 21.33, with off-spinner Nathan Lyon the only other player to record as many dismissals (nine wickets at an average of 25). 

The hosts initially named an unchanged 15-man squad for the remainder of the Tests in Melbourne, Sydney and Hobart but have added bowler Scott Boland to the group while the medical team continue to assess the fast-bowling group.

Langer has also confirmed Marcus Harris will open in the third Test, despite the left-handed batter managing just 38 runs across four innings, knowing Australia will retain the Ashes if they avoid defeat at the Melbourne Cricket Ground.

Dawid Malan insisted the time for talking is over and England must now prove themselves in Melbourne after a dismal start to the Ashes.

England have been outclassed in the opening two Tests, suffering a 275-run defeat in Adelaide after a nine-wicket beating in Brisbane.

The tourists are without a win in 12 Tests in Australia – their joint-longest such run Down Under (also 12 between January 1937 to February 1951).

The third Test starts on Boxing Day at the MCG, with bowler Mark Wood revealing England have held "brutally honest" meetings before Saturday after disappointment last week.

Captain Joe Root also provided a scathing post-match summary of his bowlers repeating mistakes from four years ago and needing to be braver with their lengths, and batsman Malan knows it is now time for England to right their wrongs as they look to keep their hopes of regaining the urn alive.

"We've done a lot of talking," Malan told reporters. "When you lose there'll always be reports that people are at each other. There definitely isn't. 

"One of the things we've been doing this series is a lot of chat amongst the players and encouraging players to challenge each other on a lot of things. 

"We've had good discussions with the coaching staff and without the coaching staff. It's vitally important that we as players take responsibility.

"Ultimately we are the ones who walk onto the field. We get all the preparation and all the knowledge we need, it's up to us to put it in place. We haven't done that well enough. 

"When we have those honest chats as players we feel we learn a lot more. Now it's about not talking any more, it's about putting it into play."

Malan has been one of England's standout performers so far, scoring 188 runs at an average of 47, with Root (175 at an average of 43.75) in close company.

However, England's next-best batter is all-rounder Chris Woakes (105), with the trio the only players to accumulate more than 100 runs from the first two Tests.

"Everyone is up for the challenge, everyone is really keen to face up to Australia," Malan added.

"We do it in white-ball cricket, we take them on, so hopefully we can get that mindset and not go into our shells and just try to survive, take the game to them.

"We are almost learning in Test matches because we haven't had that preparation. A lot of the guys haven't played in Australia so are trying to find ways of facing bowlers they haven't faced before but also to get used to bounce here. 

"I know there's a lead-up to dismissals and how bowlers set you up, but a lot of our dismissals were probably soft in the sense that we could have left them. You still have to score, but it's about making the right choices under pressure, myself included. 

"If you look at the way they have batted, the ones who have done really well, they've left really well so it's a good learning curve for us. Hopefully it's not too late."

Australia coach Justin Langer has confirmed Marcus Harris will play the Ashes Boxing Day Test at the MCG against England despite his poor run of form.

Harris has only managed 38 runs from four innings during the series and averages 22.19 during a 12-game Test career with only two half-centuries from 23 innings leading to pressure on his spot as David Warner's opening partner.

Australia's 2-0 Ashes lead has helped ease some pressure on Harris but Langer publicly threw his support behind him in a further boost for the embattled Victorian.

"He'll play in the Test, no worries about that," Langer told reporters on Thursday. "This is his home ground. He's played a lot at the MCG.

"He hasn't made the runs he'd like to so far, but he dominates domestic cricket so he knows that he knows how to play.

"He's a fantastic bloke around the squad ... And we know he's a very good player. For him and for us we're hoping he plays well and gets a good partnership with Davey Warner in this Boxing Day Test match."

Australia's opening partnerships in the four innings this Ashes have equated to an average of 17.75, with stands of 10, 16, four and 41.

Langer added: "We're really confident Marcus has got what it takes to be a successful Australian opening batsman and what we see in the nets, what we see in domestic cricket all adds up to what is potentially a very good Test career.

"One of the building blocks of a great team is the opening partnership and top three. We're determined to get that right."

Former Australia left-handed opener Langer endured similar struggles during his playing career but was backed by ex-captain Steve Waugh.

The 51-year-old coach, who worked with Harris during their time in WA, said it was important Harris felt "important to the team" to bring out the best in him.

"That's absolutely one of the most important things in life, knowing people have got your back," Langer said.

"My experience, when Steve Waugh, Ricky Ponting, Mark Taylor or Allan Border said 'you're in the team', you feel like Superman. You feel like you're important to the team and Marcus Harris is important to the team."

Mark Wood expects a response from England after stern words from Chris Silverwood and a discussion among senior players following their poor start in the Ashes.

Joe Root's side have been comfortably outplayed by Australia in the opening two Tests, most recently succumbing to a 275-run defeat in Adelaide after a nine-wicket loss in Brisbane.

Another crushing blow at the Adelaide Oval leaves England needing a minor miracle to overturn a 2-0 series deficit, the tourists now without a win in 12 Tests in Australia – their joint-longest run Down Under (also 12 between January 1937 to February 1951).

The third Test starts in Melbourne on December 25 and Wood hopes an in-depth chat between players, and an honest evaluation from Silverwood, after defeat in the second Test will leave England in better shape.

"We obviously review the game, chat about what we did well, what we didn't do well, but this time it was sterner from Chris Silverwood," Wood said.

"To hear [Chris Silverwood] speak like that – not because he's under pressure or anything – but to hear him speak like that rather than just being his usual coaching self, he was actually annoyed and wanted a change.

"Hopefully it comes at the right time for us to catch a spark.

"Stokesy [Ben Stokes] and Joe Root spoke to the group about… basically a bit of a kick up the bum saying 'this isn't good enough'.

"We've talked in-depth about how things can get better. Not just words or cliched words, we actually set out what we're going to do in Melbourne practice-wise, what we're going to do differently."

Wood did not feature in Adelaide despite impressing in the opening Test, with Stuart Broad and James Anderson leading the tourists' bowling attack in the latter pink-ball outing.

Right-arm paceman Wood is expected to return for the next Test to offer Root an alternate option to his attack after the England captain criticised his bowlers' lengths.

Root provided a scathing summary earlier in the week as he claimed his bowlers "needed to be braver" and had repeated mistakes from four years ago, but Wood believes his captain's words did not come across in "the way he totally wanted" to.

Wood added: "I don't think there's any friction between the bowlers and the captain. It's not like that at all."

Nevertheless, it is now or never heading into Saturday and the Durham quick believes England can still change their fortunes around.

"We've got to believe we can turn this round," Wood said. "We haven't shown our best stuff yet. We know that Australia have played really well. If we can match them then we believe we can win Test matches here.

"We've just got to up our game in all three areas. At the minute, Australia have scored 400 twice, we've had batting collapses and we've dropped catches.

"We've got facets of the game that need major work. We've now got a couple of days to stop thinking about cricket, get away in Melbourne and enjoy the lead-up to Christmas."
