In a battle of the league's bottom two teams, it was Roar who impressed in a dominant display of speed and strength.

Cernak got  Roar off to the perfect start with a brilliant individual effort in the 13th minute.

He combined with Tim Smits to get around the diving AIS keeper Aaron Lennox and slot  into an open goal.

Both teams had chances go begging in the first half, first Eli Babalj hit the woodwork for the AIS from close range, before a long range Smits bullet in the 26th minute slammed into the crossbar.

Roar were unlucky not to go further ahead in the 36th minute. Firstly a courageous Lennox dived  at the feet of Kenneth Dougal, only to have the ball fall to Antony Schiavo who shot wide of the open goal.

The AIS struggled to penetrate the Roar defence, trying in vain to use the aerial route while Roar worked the ball, aided by the experience of three over-age players.

Brisbane started the second half searching for their second goal and it didn't take long before they had it.

Cernak was on the end of a great long ball from Luke Bratten, got around two defenders with ease and put it past Lennox who had little chance of saving the shot.

Smits was in the thick of it as Brisbane kept attacking, firstly turning and shooting which forced a top save by Lennox in the 64th minute and nearly setting up a goal seconds later.

The AIS had a goal ruled offside by the linesman in the 68th minute, after a long range Marc Warren shot wasn't contained by Roar keeper Matt Ham and Terry Antonis put it into the back of the net.

The game finished in a flurry, a 73rd minute curling Stefan Vrbesic free-kick hit the crossbar with Babalj failing to beat Ham in a one-on-one 10 minutes from time.
