Two goals in two minutes helped Perth come from behind to win 2-1 in Brisbane on Thursday night, with the Roar left to rue another decision that didn't go the club's way.
The Roar were in the box seat, leading 1-0 late in the second half and searching for a decisive second goal, until Perth duo Andy Keogh and Diego Castro combined to send the Roar to their sixth loss from 12 games.
Returning off the bench after a three-game absence due to a groin injury, Keogh seemed to bring Castro to life. The pair immediately looked lively but it wasn't until the 80th minute that they turned the game on its head.
First it was Castro setting up Keogh, then two minutes later the roles were reversed as Castro put Perth in front.
Until that point the Roar had looked comfortable, without managing to land the killer blow.
Massimo Maccarone broke the deadlock in the 38th minute, controlling a pin-point Fahid Ben Khalfallah pass to perfection before holding off two defenders and knocking a deflected shot into the net.
It was the 38-year-old's sixth goal from 12 starts, but the Roar were left to rue the fact that there should have been more.
Maccarone was denied a second early in the second half, the linesman raising his flag as the Italian fired his shot past Liam Reddy despite replays showing the Italian to be onside.
Minutes later he was denied when Reddy bravely stood in front of a rampaging Maccarone and Corey Brown to block what appeared a certain goal.
The goalkeeper was forced from the field with vision issues after the collision as the hosts continued to press for a second in front of 7031 at Suncorp Stadium.
Possession was evenly shared in the first half, but it was Brisbane who made the best of it.
Teenage striker Nicholas D'Agostino had two opportunities to open the scoring, first flashing over the bar just outside the box then heading over the bar moments later.
Luke De Vere started in his first game for the Roar since a knee injury sustained in October, promoted from the bench after Daniel Bowles felt some soreness in his reconstructed knee.
