Hundreds of police officers will escort a procession of bikies as they ride to the funeral service of assassinated former Rebels boss Nick Martin, vowing the community has nothing to fear from the outlaws.
It will be one of the biggest gatherings of bikies in recent times, but police said they would outnumber them at all times.
"Our aim is to make sure everyone goes home safe," Assistant Commissioner Brad Royce said.
Mr Martin was shot dead while watching a drag racing event at the Kwinana Motorplex on December 12.
Public urged to avoid Scarborough Beach Road
Police have urged the public to avoid Scarborough Beach Road if possible between 10:00am and 2:00pm, which is expected to become congested as the bikies leave a funeral home in North Perth and head towards West Coast Highway.
From there, the estimated 150-200 bikers and the police accompanying them will head north towards Marmion Avenue and then inland towards the Pinnaroo cemetery for the service.
Bikers from some other outlaw motorcycle gangs are also expected to take part.
"Whenever you bring a large number of people that live a life of violence together, we always have concerns," Assistant Commissioner Royce said.
"But again we have a significant number of officers on the ground and at other locations, and again we think we've got this one sorted.
"The community don't have anything to fear. Police will outnumber everybody in the area."
Police to bolster ranks for 24 hours
Police are increasing staff over a 24-hour period for the funeral and will have a significant presence along the funeral route, at the service, at the wake, at bikie clubhouses and licensed premises after the event and into Wednesday.
"There will be no reduction or limitation on services elsewhere in the state," Assistant Commissioner Royce said.
"We have significant numbers of officers on duty tomorrow, in the hundreds, just for this matter. There will be no impact on other services."
Police confirmed a small number of people from interstate were coming for the funeral.
None were from New South Wales, because of the closed border.
The others would have to fill out a G2G COVID-19 form like anyone else.
Another biker was shot in the arm by the same bullet that passed through Mr Martin while a five-year-old boy also received minor injuries.
The State Government has offered a $1 million reward for information relating to the murder.
Police set up Operation Ravello to find the killer and have since carried out raids and executed search warrants on bikie-linked properties across Perth.
Mr Martin's family asked for $8,000 taxpayers assistance from the Department of Justice for the funeral.
But Justice Minister John Quigley refused the request, saying "hell will freeze over before we pay for a bikie's funeral".
