Australia began the final group phase of AFC World Cup qualifying with a comfortable 2-0 win over Iraq on Thursday thanks to goals from Massimo Luongo and Tomi Juric.
The Socceroos dominated for long periods in Perth and got their reward in the 58th minute as QPR midfielder Luongo, slotted home the opener, with Juric providing the assist.
And the points were made safe by Juric when he poked home six minutes later, converting from Mark Milligan's flick-on from a corner.
Ange Postecoglou's men will look to make it two from two in a tough Group B that also features Japan and Saudi Arabia when they take on the United Arab Emirates in Abu Dhabi on Tuesday.
Australia could have opened the scoring inside the opening minute, Juric forcing Mohammed Hameed into action.
Brad Smith then found Mathew Leckie with a pinpoint cross but the Ingolstadt forward's looping header struck the post.
Iraq went close to breaking the deadlock against the run of play, only to see Ahmed Yaseen Gheni's curling effort fizz wide of Mat Ryan's goal.
