Melbourne Victory suffered a 6-0 loss to Brisbane Roar in the Foxtel Y-League on Sunday.
A Daniel Leck hat-trick and goals from Oliver Duncan, Lleyton Brooks and Mirza Muratovic saw Brisbane to its win in the Conference A clash at Lions Stadium.
Brisbane was clinical in the first half, including scoring four times in the opening 20 minutes.
Duncan and Brooks struck before Leck netted from the edge of the area in the 16th minute.
Leck made it 4-0 four minutes later and completed his hat-trick with a curling effort.
Muratovic grabbed Roar's sixth when a deflection fell to him as Brisbane made the most of its chances in the first half.
Victory improved in the second half, with Jack Palazzolo denied in a one-on-one, as it fell to defeat.
Head coach Gareth Naven's post-match thoughts
"When you don't have the discipline to produce your performance principles in regards to how we defend, how we attack, the transition moments and we don't do that consistently, that's what you get and that's what happened. You need to be able to perform, set up, do things early, as quickly as possible, and we didn't do it enough and we got punished.
"We need to get better on the ball and keep the ball for more than three passes, rather than play basketball with the opposition. You play basketball with the opposition and the opposition use the ball better than us. The challenge for our group is can we learn from it and do we want to get better?"
