Nine members of the Mongols outlaw motorcycle gang are now facing murder charges over the killing of alleged gang defector Shane Bowden, after police made another arrest.
Adam John Murphy, 37, of Wanora had his case mentioned in Brisbane Magistrates Court on Wednesday after his arrest the previous day.
He was not brought into court, but a Legal Aid lawyer asked for the case to be listed again in the same court next month.
Bowden, 47, was gunned down in the driveway of a residence at the Gold Coast suburb of Pimpama in October.
A total of 21 rounds were fired - 19 from a machine pistol and two from a shotgun - before the offenders ran to a waiting silver commodore and fled, Queensland Police allege.
A "so-called brotherhood and code of silence" employed by the outlaw gang was steadily being dismantled, Detective Superintendent Brendan Smith said on Wednesday.
The other eight men fronted court on Monday after being charged with murder over the weekend, including Ian Ronald Crowden, the president of the Brisbane West chapter of the Mongols.
Gold Coast criminal lawyer Michael Gatenby said he would be "very surprised" if a murder charge stuck for the bulk of the defendents given the prima facie case.
Bowden was initially a member of the Finks criminal bikie gang, and part of its "terror team" jailed over the Gold Coast's so-called ballroom blitz brawl in which three people were shot and two stabbed in 2006.
After his release, it's understood he defected to the Mongols but was booted out and rejoined the Finks just before he was shot.
All nine men are due to have their cases mentioned again on August 2.
