Sydney FC came in hopeful of building on their good start against Newcastle in Round one but Brisbane showed how much more work Sydney really have to do, and perhaps that Newcastle may be in a spot of trouble as well.
The match started well enough with both teams struggling to break through the opposition defense while early injuries forced both teams to change their plans.
Playing with a lone striker can always be risky and in the 26th minute Besarat Berisha went down injured forcing Brisbane's only striker off the park, a significant game changer.
Sydney faced the same fate straight after with their key player Aessandro Del Piero going down forcing Sydney to play without their star and from there they looked lost.
Seven minutes after Del Piero left the park Brisbane had the lead as Tomas Broich's free kick was sent to the far post, with Vedran Janjentovic struggling to get to the ball it allowed Matt Smith to head home.
It didn't take long for Brisbane to make it two as Henrique, who replaced Berisha, made it two just one minute later with Ivan Franjic's header crossing the face of goal and coming off the Brazilian's thigh.
Sydney looked stunned and right before half-time Brisbane made it three as Nick Carle gave away possession allowing Matt McKay to send a through ball for Jade North who was able to bury it for his first goal since 2008 making it 3-0 at the break.
The second half was more of the same as Brisbane completely dominated Sydney FC and could have four early on as McKay hit a long range effort that Janjentovic was able to deal with.
A rare chance came Sydney FC's way as they responded to that opportunity with Joel Chianese able to get a shot away but he could only find the side netting.
A counter saw Brisbane score again as Henrique was able to find the back of the net but his run was too soon as he was offside for Franjic's through ball.
It continued to be all Brisbane and Smith had another chance as he was able to head toward goal only for Janjentovic to parry the ball away before diving on Henrique's attempt on the rebound.
Brisbane finally did find their fourth goal as Ivan Franjic sent a cross in that found Broich who was able to sneak in and make it four, humiliating Sydney FC.
