Midfielder Steven McGarry's wonder-strike gave Perth Glory a 1-0 victory and heaped more misery on struggling A-League champions Brisbane Roar on Friday night.
McGarry's 35-yard stunner just before halftime was enough to secure the Glory their first back-to-back wins of the season and leave new Roar coach Mike Mulvey ruing what might have been after the hosts squandered numerous opportunities.
In front of 11,352 fans, the Roar spent most of the second half attacking the Glory's penalty area but the home team failed to convert with star striker Besart Berisha particularly guilty of fluffing chances he'd normally bury.
The Albanian, who controversially won a penalty which he then converted to seal the Roar's grand final win over the Glory at Suncorp Stadium back in April, had at least three clear chances to score but endured a rare off-night in front of goal.
Brazilian Henrique hit the crossbar while midfielder Erik Paartalu and youngster Ben Halloran also came close but the Glory somehow held firm to deny the Roar an equalising goal in a lopsided second-half.
McGarry's classy strike, which came after he was given space from a clever flick-on from Smeltz, lifts the Glory to fourth place with 17 points, ahead of Melbourne Victory on goal difference.
The Roar, who replaced head coach Rado Vidosic with Mulvey during the week, remain ninth with just three wins from 12 matches.
The Roar also suffered a late blow with substitute Jack Hingert limping off in the dying minutes of the match.
Glory coach Ian Ferguson praised his team's backs-to-the-wall effort as Perth secured their first victory on the road this season.
"I thought the desperation and defending was exceptional," Ferguson told reporters.
"They were throwing their bodies on the line and they kept the two banks of four to make it difficult for them.
"Brisbane kept coming at us, had a couple of chances where we've rode our luck a little bit but, you know what, we've played better and got nothing ... we've got a great result away from home."
Mulvey chose to take the positives out of his team's efforts, saying on another day the Roar would have come out on top after their dominant second half showing.
"The good news is we're creating chances, just a little bit low on confidence at the moment," he said.
"Yes, disappointing tonight, good that we created some chances and we know we've got players to score goals, we just need a bounce of the ball to go our way."
Mulvey said Hingert received a knock to his hip late in the match and will be monitored over the next couple of days but he was hopeful the defender's injury wasn't that bad.
The Roar travel to Adelaide on Boxing Day in their next match while the Glory return home to host Western Sydney Wanderers on December 27.
