The Roar raced out of the blocks with midfielder Katrina Gorry finding the back of the net after only 25 seconds to set the tone for the match.
A double to Alira Toby wrapped up the result for a Brisbane side which was hardly threatened by their error prone Sydney FC opponents.
The Sky Blue lost possession only moments after the kick-off and before they could blink Gorry had buried the ball into the top corner of the net.
It was one way traffic for most of the match with Brisbane controlling the tempo and possession.
Toby was fortunate with her first goal when she bundled the ball into the goal after it seemingly struck her arm.
It wasn't until deep into the second half when Sydney finally troubled the score sheet, but it wasn't without a little bit of controversy.
Striker Lena Khamis was taken down in the box by a high foot from Roar defender Summer O'Brien and was awarded a penalty only after much deliberation between the referee and her assistant.
American import Emily Sonnett obliged from the penalty spot to give Sydney hope of snatching a point.
However, it was Toby's lucky day and the Brisbane striker clinched her second of the match with a no look header which ensured the visitors would take all three points from their first match of the season.
