With the emphatic win Brisbane now share the top of the league with Sydney, Canberra and Melbourne Victory in what is proving to be a tight season making such big scores a vital commodity.
The first half was much less exciting and quite different as it looked like Western Sydney would take the match if based on the first half as Brisbane really struggled to have a big impact.
It took a long time for either side to really get going in a tight first half that saw few chances but the one real chance that came was put away as Catherine Cannuli got past her defender and chipped the keeper to give Western Sydney a 1-0 lead at the break.
The second half proved much more exciting with a goal coming after just five minutes when Caitlin Cooper held back Katrina Gorry allowing her to score an equalizing penalty.
Just two minutes passed and Brisbane had the lead as a through ball allowed Hayley Raso to run on through of the defense and calmly slot the goal that would put her side in front.
From there the match settled a little but Brisbane still firmly had control as they made life difficult for the Wanderers who fought to get back in to the match.
With nine minutes to play Brisbane wrapped things up as Amy Chapman found Gorry with a solid cross allowing her to easily head home the clincher.
In stoppage time Gorry came up for Brisbane again as she was able to sneak in and seal her hat-trick to rub salt in the wounds of Western Sydney.
