The RBB generates an incredible atmosphere at A-League games through their chanting and singing. There's even a school of thought that suggests the group ought to be considered a triumph of sorts because members of the various ethnic groups which make up Sydney's multi-cultural western suburbs have united as one to join the RBB and support the Wanderers.

However, there has also been numerous complaints made about incidents that have involved some members of the group and the media has publicised the clashes they have had with the police over the years.

During last Anzac Day's match against Perth, RBB supporters walked out of Pirtek Stadium at halftime in protest after pepper spray was allegedly used by police in response to a flare being set off. There were reports police were injured in the violence.

The confrontation continued outside with the supporters infuriated by what they believed was an overreaction by police. There was a newspaper report published in early 2014 which intimated while the majority of RBB fans were acknowledged as being well behaved and good supporters, there was said to be a hardcore element who police were concerned could potentially lead to criminal behaviour.

Police made it clear at the time they would not allow the formation of the old English football's "firms" a group of hooligans who fight like-minded supporters from rival clubs. It is understood at the time police had gone to a lot of trouble to identify those with a penchant for creating trouble.
