A trademark Tim Cahill header ensured Australia made a winning start to the Ange Postecoglou era with a 1-0 victory over Costa Rica at Allianz Stadium.

After a nervous start that saw them almost concede an early own goal, the hosts settled into their work and dominated a goalless opening period.

Cahill came off the bench in the 52nd minute and produced the defining moment 17 minutes later when he headed home a curling Tommy Oar corner. It was his 29th international strike, bringing him level with level with Damian Mori as Australia's leading goalscorer.
