A Hells Angels gang associate was caught with more than 300 grams of methamphetamine and a stash of cash and firearms in a police gang unit crack-down.
The man was arrested in Albany after an investigation by the motorcycle gang unit of the police organised crime agency Ofcanz.
Detective Senior Sergeant Lloyd Schmid said a search of the man's vehicle found 18 grams of methamphetamine.
A later search of his home found a further 300 grams of methamphetamine with an estimated street value of between $128,400 and $300,000, and tens of thousands of dollars in cash.
Police also found a cache of firearms including a Glock handgun, a 357 Magnum revolver, two .22 calibre rifles, one with a pistol grip, hundreds of rounds of ammunition and five stun guns.
