Ilkay Gundogan went close when he curled a low effort goalwards from outside the box, but the well-struck effort flashed just wide of Matthew Ryan's left-hand post.

Matthew Leckie perhaps should have given Australia a shock lead inside the first 10 minutes when he dribbled past Benedikt Howedes before firing wide inside the area.

Nathan Burns was guilty of wasting a great opening for the Socceroos on 13 minutes when he met a cross from around six yards out with a wayward header.

Mario Gotze picked out Mesut Ozil with a cross-field pass on the edge of the box, but the Arsenal playmaker could only drag his shot wide, before Marco Reus's instinctive finish was correctly ruled out for offside moments later.

However, the Borussia Dortmund star was not to be denied and the playmaker poked home on 17 minutes after a clever pass from Sami Khedira with the outside of his foot.

Reus should have made it 2-0 on 22 minutes when he profited on a loose pass in the Australia defence but the attacking midfielder could only hit the side-netting with just Ryan to beat.

A promising break from the visitors saw Crystal Palace midfielder Mile Jedinak let fly from distance and he brought out a good stop from goalkeeper Ron-Robert Zieler.

Leckie should have done better when he was sent scampering clean through on goal when he stood on the ball with just Zieler to beat just after the half-hour mark.

Troisi restored parity on 40 minutes when he met Burns's cross with a powerful header to mark his second goal in as many games for his country.
