Several members of European motorcycle gangs have been refused entry to Australia.
Two German members of the Gypsy Jokers Outlaw Motor Cycle Gang (OMCG), one member of the gang's Norway chapter and two Spanish gang associates were refused entry at Perth Airport.
The German men, aged 33 and 61, arrived in Perth on a flight from Hong Kong on April 15th.
The Spanish men, aged 43 and 44, also arrived on Monday on a flight from Dubai.
The 34-year-old Norwegian arrived on a flight from Singapore on Wednesday April 17th.
All five men were questioned by officials, who said the men travelled to Perth to attend an event celebrating the 50th anniversary of the Gypsy Jokers OMCG.
The men were all holding visas which were cancelled, on the basis that they presented "a risk to the health, safety or good order".
Australian Border Force (ABF) regional commander is Rod O'Donnell.
"These gangs pose a significant threat to our community and are known to be involved in serious criminal activity including drug trafficking and violent crime," he said.
"Any non-citizen involved with a criminal organisation, including outlaw motorcycle gangs, can expect to have their Australian visa cancelled on arrival and be removed from the country."
The men were held in a Perth immigration detention centre, pending their removal from Australia.
ABF said the Spanish nationals were removed on Tuesday night, with the Germans and Norwegian removed on Thursday.
