Koby Abberton

In 2003, Abberton became entangled in a court case resulting from the death of a Sydney underworld figure, Anthony 'Tony' Hines. His older brother, Jai, was charged with the 2003 murder of Hines and was acquitted 2005, claiming self-defence, even though he admitted to shooting Hines.[15]

Appearing in court on 5 August 2003 on three counts of false statements to police, Abberton pleaded not guilty to being an accessory after the fact to murder[16] but changed his plea to guilty on 21 March 2004. Despite his brother's acquittal of criminal charges, on 24 November 2004, NSW District Court Acting Judge Brian Boulten handed Koby Abberton a suspended nine-month jail sentence after being found guilty of perverting the course of justice in the same matter.[2][10] During the time of these criminal proceedings, Abberton lost a string of lucrative sponsorship deals he had contracted through his professional surfing career. Despite surfing sponsor and surfwear giant Oakley initially sticking by Abberton,[17] they later withdrew a $250,000 annual sponsorship.[18]

The Abberton brothers and numerous members of the Bra Boys received negative coverage in Australian media following the racially charged 2005 Sydney race riots originating between opposing ethnic mobs on Cronulla beach. The negative media coverage motivated further rioting of the same racially charged nature on a string of other popular Sydney beaches, said to be an attempt to address the reported incidents of assaults and intimidatory behavior by groups of non-locals, some of whom were identified in earlier media reports as youths of Middle Eastern appearance from the suburbs of Western Sydney. In the lead up to the riots, Abberton spoke to The Daily Telegraph about the assault of a lifeguard that sparked the incident, claiming:

"The reason why it's not happening at Maroubra is because of the Bra Boys. Girls go to Cronulla, Bondi, everywhere else in Sydney and get harassed, but they come to Maroubra and nothing happens to them. I read all this stuff about kids getting harassed because they want to have a surf and I say 'are you kidding?' The beach should be for Aussie kids. But if you want to go to beaches and act tough in groups you better be able to back it up. If these fellas come out to Maroubra and start something they know it's going to be on, so they stay away."[19]

Following the riots, in which the Bra Boys did not claim any involvement, Maroubra was the target of retaliation by Middle Eastern gangs. The Abberton brothers then held well-publicised meetings with other groups to help ease tensions.[20] "I think that this is the start, the boys have agreed to come down and talk to us, to start some dialogue between the groups, you know, to try and ease some tension", said Sunny Abberton in a group interview on The 7.30 Report.[21] Koby Abberton, his brothers, and other member of the Bra Boys were labeled as playing catalyst to the riots with Abberton singled out as the main culprit. Later, Abberton disputed the claims that he had attempted to fuel the riots, going on to tell The Sydney Morning Herald that he was "ashamed to be Australian that day" and had attempted, alongside his brothers and other Bra Boys to deflect and suppress the racially charged riots.[22]

Abberton was declared bankrupt in 2006, with debts in excess of A$1 million. These included debts of A$940,000 to the National Australia Bank, A$150,000 to the NSW Crime Commission, and A$50,000 in legal fees relating to his unsuccessful defence to charges of perverting the course of justice.[23][24]

In 2008, Abberton plead guilty to assaulting an off-duty police officer in Honolulu. He was given a three-day custodial sentence.[4]

The Mavis Abberton Foundation was set up by the Abberton brothers in an attempt to protect children of drug-dependent parents and children whose parents are in prison. The Foundation was named after the Abberton brothers' grandmother Mavis, who provided as their mother for most of their childhood while their own parents were incapable of providing a stable and guided environment. The Foundation attempts to suppress the prevalence of "lost children in broken-homes" and promotes a solace for those who may otherwise resort to drug dependency and criminal activity as a result of their environment.[23]

In 2007, it was reported that there were plans for an exhibition cricket match to be played between members of the Bra Boys and the Compton Cricket Club (CCC), a disadvantaged cricket team made up of former gang members from south central Los Angeles, to help raise the profile of the Foundation during the CCC's inaugural tour to Australia.[25]

Inspired by the friendship and brotherhood codes instilled by the Bra Boys, a clothing line to reflect the importance of solid bonds between friends and family entitled MyBrothersKeeper Clothing, sometimes referred to as MBK Clothing. Official members of the Bra Boys, including Abberton, have the "MyBrothersKeeper" slogan permanently tattooed on their bodies. Members of the Bra Boys and those who have purchased items from the clothing range are often referred to by the Bra Boys as MBK Soldiers.[8]
