BIKIE gangs in the firing line of Queensland's tough laws are migrating across the NSW border to the Northern Rivers, according to Queensland police and a former Gold Coast detective.
Bond University criminologist and former Queensland police officer Dr Terry Goldsworthy said he believed bikies were fleeing to escape mandatory sentencing of 25 years in prison.
"I think it would be foolhardy to think bikies, who are finding life difficult on the Gold Coast, wouldn't be going across the border where there are few restrictions on them meeting or getting together," he said.
"Whether they are going across the border permanently or just going across temporarily is a question we don't know."
Recent News Limited reports showing a Queensland Polair video of members of the Rebels Ballina chapter riding north on the Pacific Motorway to meet Tweed-based Odin's Warriors and Mongols was evidence of this migration, he said.
A Queensland police spokeswoman said police were aware that criminal motorcycle gangs were active on both sides of the border and they did not respect boundaries.
"It is not uncommon for law enforcement agencies to witness criminal motorcycle gangs moving between states," she said.
"In partnership with all other law enforcement agencies, including New South Wales Police Force, we will continue to work towards eliminating criminal gangs."
Dr Goldsworthy explained there were two levels of bikie gangs - those who overtly committed violent offences in the public eye and the more underground, covert operations.
"The Finks feature prominently for acts of violence and the Bandidos feature too," he said.
"I think some of the other clubs that we don't often talk about are the sleepers such as the Black Uhlans, the Rebels and the Hells Angels.
"I would be surprised if law enforcement weren't keeping their eyes on the gangs that aren't out there doing the silly public offences because they would be ones doing organised crime."
