Australia were unable to finish on a high in the third round of World Cup qualifying as they fell to a 1-0 defeat in a dead rubber against Saudi Arabia in Jeddah. 

A 2-0 loss to Japan last Thursday ended the Socceroos' hopes of earning automatic qualification to Qatar 2022 with Salem-Al Dawsari's second-half penalty securing top spot in Group B for the Green Falcons. 

Awer Mabil narrowly missed the target from Martin Boyle's cross in the 12th minute and the latter had a goal ruled out following a lengthy VAR review shortly before half-time. 

Graham Arnold replaced Bruno Fornaroli with debutant Nicholas D'Agostino at half-time but Saudi Arabia continued to control possession. 

The hosts were awarded a penalty when James Jeggo clipped Sami Al Najei and Al Dawsari coolly guided the spot-kick into the bottom-right corner. 

Australia did not go close to finding an equaliser – Ajdin Hrustic wasted their best opportunity – and needed Mat Ryan to stop Firas Al Buraikan making it 2-0 in the final 10 minutes.

The Socceroos must now take on the United Arab Emirates for a place in an intercontinental play-off against a South American team, where a place in Qatar will be on the line.
