Marcus Harris insists Tim Paine has the full backing of his Australia team-mates after the wicketkeeper stepped down as Test captain.

Paine resigned as Australia's skipper in the longest format last week due to the emergence of a lewd text exchange with a former Cricket Tasmania colleague back in 2017.

At the time, Paine was found not to have breached Cricket Australia's code of conduct and remained as Test captain, having taken up the position in 2018 following Steve Smith's demotion in light of the sandpaper ball-tampering scandal.

Paine will remain involved with the Australia squad, having been named in the selection to face England, though a new captain is yet to be announced.

Tasmania chairman Andrew Gaggin hit out at CA's treatment of Paine and while Harris revealed the Australia squad were shocked, he says there is full belief that Paine will play a key role in their attempts to retain the Ashes.

"People were obviously a bit shocked but we've got a lot of good leaders around our group," Harris told reporters.

"It's not ideal but someone's going to have to step up and lead from the front.

"Painey will still be around and can still show leadership in many different ways but we're looking forward to getting into camp and getting on with it.

"I think you'd probably still argue that he's still the best gloveman in the country.

"I know he's got all the support of the players and like I said, all that other stuff is up to people above me."
