Six people have been arrested following a string of cross-border raids in Queensland and NSW targeting the Rebels outlaw motorcycle club.
The arrests top off a three month investigation into alleged drug trafficking by members of the bikie gang's Ballina chapter.
Police believe Rebels members and associates were moving drugs from the north coast chapter over the border to the Gold Coast, where it was being sold to buyers.
Queensland police joined the investigation and focused on the gang's acclivities on the Gold Coast.
On Wednesday police in both states executed a string of raids at several properties.
On Wednesday night one search at a home in Bangalow, near Byron Bay, was still going.
Police allege they have found two rifles, a shotgun, methamphetamine, cannabis, cocaine, steroids and cash.
Among those arrested in the cross-border raids is the alleged vice-president of the Rebel's Ballina chapter, police say.
The 31-year-old Bangalow man was charged with a string of offences including drug trafficking and participating in a criminal organisation.
A 33-year-old man was also arrested for hindering police at the Bangalow search warrant.
In Queensland two men, 27 and 31, and two women, 21 and 24, were arrested and charged with drug offences.
The 27-year-old was also charged with participating in a criminal organisation.
Richmond Local Area Command Detective Inspector Cameron Lindsay said as had been the case for years, police were regularly gathering intelligence on northern NSW bikie chapters.
"Whenever we catch them breaking the law, whether it's through running a red light or through manufacturing drugs, you can rest assured we will arrest and charge them," he said in a statement.
"We work closely with our colleagues over the border in Queensland and regularly share intelligence and resources to tackle those criminals who attempt to conduct their illegal activities across state boundaries."
Police expect further charged to be laid and they were not able to confirm court dates for those charged.
