Roar broke the deadlock early in the second half, Scott McDonald heading in Bradden Inman's cross, although Matt Acton in the Victory net will have been frustrated after getting a hand to it.

Matthew Ridenton made it 2-0 12 minutes from time, nodding home after a flowing team move, with Andrew Nabbout's subsequent penalty soon after coming too late to inspire a turnaround.

The result gives Warren Moon his first win in charge and consolidates Roar's position in fourth, giving it an eight-point cushion in the finals qualification places. Victory, meanwhile, remains second-from-bottom.
