A Bruno Fornaroli double earned Perth a 2-0 A League Men win over Brisbane in Launceston, lifting Glory off the bottom of the ladder and putting the Roar last.
The Uruguayan scored from the penalty spot in the eighth minute and settled the contest with a clinical quick turn and shot in the 73rd minute.
The win lifted Perth three spots to ninth and pushed Brisbane down one place to last, but the bottom four are all on 11 points, with eighth-placed Western Sydney just one point above.
It was the first of three games in eight days in Launceston for Perth, who have still played fewer games than any other team.
Brisbane, who are winless away from home, had 17 shots to seven and dominated the final 20 minutes of the first half, creating several chances, but couldn't finish off.
Fornaroli blasted his spot kick down the middle as Brisbane's debutant goalkeeper Jordan Holmes dived to his right, after Henry Hore fouled Pacifique Niyongabire.
It was Perth's only shot of the first half despite them dominating territory and possession through the first 25 minutes.
Dennis Olsen had a close-range shot saved at point-blank range by Perth's veteran goalkeeper Liam Reddy who was playing his first ALM match of the season following shoulder surgery.
Olsen had another shot blocked and was off target with another while Matti Steinmann put a volley and header wide.
Perth finally shook off their attacking lethargy in the 57th minute with Nick Fitzgerald having a shot deflected wide for a corner.
Seconds later captain Brandon O'Neill was just off target and Callum Timmins shot straight at Holmes, before Fornaroli bagged his second goal.
Reddy saved from substitutes Luke Ivanovic, Cyrus Dehmie and Anton Mlinaric, but Brisbane remained goalless.
Former England international striker Daniel Sturridge came off the bench in the 71st minute and had one off-target attempt.
Perth defender Aaron Calver came off early in the game after landing awkwardly on his back.
