A Comanchero bikie who patched over from rival outlaw club the Rebels has been found dead at a luxury resort in Western Australia. 

Jason Kemp was discovered floating face down in the private pool of a villa at The Pearle of Cable Beach about 12.10pm on Saturday.

Emergency services were called and rushed to the site but Kemp, aged in his late 30s, could not be revived - with WA detectives now investigating how he died. 

He had been staying at the five-star resort near the popular tourist beach at Broome, in northern WA, with his girlfriend.

It is not known how he died but police are at this stage treating it as accidental with homicide detectives not involved, reports The West Australian. 

The villa remained cordoned off by police tape on Sunday, however, as investigators try to determine exactly what happened.

It is understood Kemp has been a member of the Comanchero outlaw motorcycle club since mid-2021.

Before that he was a full member of the Rebels.

The switch, usually considered a great offence in bikie circles, occurred after he was savagely beaten by a fellow Rebel in May of that year inside Casurina Prison in WA.

Kemp, who was doing a stint for drug and traffic charges, was left with severe head injuries that required a lengthy hospital stay. 

WA Police said the bashing was a result of an internal dispute between the two club members and was not linked to tensions over the assassination of Rebels boss Nick Martin months earlier. 

Martin was gunned down by a sniper at the Kwinana motorsport complex, with a former soldier linked to the international mercenary group Shadows of Hope later pleading guilty. 

By July 2021, Kemp was blacking out his large Rebels forearm tattoo on photos he posted online.

Later that month he posted a photo showing the word 'Comanchero' inked onto his forearm over the old tattoo.

Kemp has a lengthy criminal history.

In addition to driving charges, including reckless driving to escape police pursuit, he was jailed in 2017 for holding his ex-girlfriend and her mother at gunpoint in a four-hour siege with police.

'It's actually quite amazing that he's been allowed in the community for this long,' state prosecutor Jason Chu said before his most recent prison stint.
