The massed ranks of the Rebels bikie gang have remained on their best behaviour as they roared out of Perth following their annual three-day party.
With a police presence to rival that which guarded Queen Elizabeth II when she visited Western Australia in 2011, members of every Australian chapter of the Rebels arrived on Friday as part of the gang's annual national run.
Closely monitored by police over the weekend, the Rebels enjoyed each other's company at their Osborne Park compound, leaving briefly for a planned run to Rockingham, which was thwarted by the unusually wet weather.
The leather-clad group instead rode to the South Perth foreshore on Saturday morning, before being led back to their headquarters by national president Alex Vella.
On Monday morning, Perth's rush hour traffic was stopped at various intersections to allow the bikies to begin their trip home.
And they will be accompanied all the way to the border by dozens of WA police, who are anticipating overnight stops at Kalgoorlie and Balladonia before the patched members leave the state.
A WA police spokeswoman said the weekend had been "relatively quiet".
"They have all gone on their way together, and will take the same route on the way out as they did on the way in," the spokeswoman said.
