Mat Leckie gave Australia's World Cup campaign a massive lift, scoring twice in a stunning and confidence-boosting 4-0 defeat of Czech Republic on Friday.
Australia's first win under coach Bert van Marwijk began with a turgid half-hour, but culminated in a rout in St Polten, Austria.
Leckie's strikes bookended Andrew Nabbout's first goal in an Australia shirt, with Milos Degenek forcing an own goal to complete the scoring.
There was even time for a debut for World Cup hopeful Daniel Arzani, who came on with six minutes remaining but saw precious little of the ball.
The contest was a final chance for each Socceroo to press their claims for a place in the 23-man squad, with four players to be cut from the provisional group by Monday.
