An execution-style murder tied to a bikie gang was organised using encrypted phones and GPS tracking apps, a court has been told.
Peter Michael Cummins on Wednesday applied for bail in the Brisbane Supreme Court on one count of murder related to serious organised crime.
Cummins is accused of aiding eight other defendants to murder Shane Bowden, 47, an alleged "turncoat" against the Mongols motorcycle club.
Two hooded gunmen fatally shot Mr Bowden 21 times in the driveway of his Gold Coast home just after midnight on October 12, 2020.
Defence barrister Scott Lynch said Cummins had been accused with "no direct evidence" of acting as a driver for the gunmen.
"There's a lot of fertile grounds for cross-examination. (A prosecution witness) is a very serious drug trafficker," Mr Lynch said.
He said the basis for applying for bail was that the prosecution case against Cummins was weak.
"It is very much a circumstantial case arising from inferences from GPS data," Mr Lynch said.
Crown prosecutor Bradley White accused Cummins of possessing a tracking device before it was attached to Mr Bowden's vehicle in the days before the shooting.
"There is some evidence the murder weapon was collected from (Cummins's) home. That's the most incriminating thing," Mr White said.
He said data from Cummins's phone linked him to the vehicle used during the shooting.
"He had possession of an iPhone 6 handset that was being used to monitor the movements of (Mr Bowden)," Mr White said.
Justice Elizabeth Wilson heard the prosecution would allege the conspiracy to murder Mr Bowden was organised via three encrypted mobile phones and Cummins had one of the handsets.
Mr White said Cummins was "closely associated" with the Mongols before and after Mr Bowden's death.
Justice Wilson told Mr Lynch she would "need convincing" to release Cummins on bail and he could otherwise apply to have the murder charge dropped in February at a committal hearing.
"I don't want to be in the position that the bail application fails," Mr Lynch said.
Justice Wilson adjourned the bail hearing to a date to be fixed.
