Paul Okon's side are on the verge of a finals place after their victory on Thursday, but face their toughest test against Japan on Sunday
Australia have all-but sealed their spot in the 2013 AFC Under-22 Championship after overcoming Timor Leste in Group E of qualifying on Thursday.
The Young Socceroos eased to a 3-0 victory at Riau Main Stadium in Pekanbaru, moving Paul Okon's second-placed team to 10 points with one match remaining.
It means Australia need just a point in their final qualifying match, against Japan on Sunday, to progress to the finals of the tournament in 2013.
Even a loss may suffice, with third-placed Singapore on seven points but trailing Australia by goal difference.
Unbeaten in four matches now, the Young Socceroos took their time in breaking down their Timor Leste, when Melbourne Victory striker Luke O'Dea finally put them in front after 40 minutes.
They then made their ascendancy count in the match's final stages, with Adelaide United midfielder Jake Barker-Daish firing a five-minute double either side of the end of normal time to ice the result.
Having shuffled his deck constantly during the campaign, Okon must now decide on his strongest XI against what is undoubtedly Australia's toughest match, against Japan.
