Football Federation Australia fined Western Sydney Wanderers $20,000 for an offensive banner raised by their fans, but will not penalise the club by docking competition points. 

The Wanderers were found guilty of bringing the game into disrepute by the FFA in relation to the homophobic banner unfurled during Saturday's Sydney derby but a suspended points penalty that's hung over the head of the club since February will not be triggered. 

Head of the A-League, Greg O'Rourke, took into account the club's belated yet strong response towards their unruly and provocative fans, banning 14 members of their active supporter group for 18-months. Western Sydney suspended the memberships of several key leaders of their supporter group on Wednesday having identified them after consultation with security. 

"The actions of the Western Sydney Wanderers spectators responsible for displaying the banner and the ensuing celebration of the banner on social media were completely unacceptable," said Head of the A-League Greg O'Rourke.

"While we have noted and were pleased with the positive proactive measures undertaken by the Western Sydney Wanderers the fine reflects the fact clubs are responsible for the actions of their spectators and managing the approval of the game day banners and activities of their active fan groups."

Western Sydney Wanderers were hit with a suspended three-point penalty in February when their fans ignited 19 flares consecutively during a football match. The suspended penalty was extended for another 12 months after their fans ignited a number of flares during the first Sydney Derby this season in early October.
