Operation Hawk was set up last October to disrupt organised crime networks in Sydney.

Officers from the Hunter Valley Proactive Crime Team and the Northern Region Support Group executed a Firearm Prohibition Order at a home on Seventh Street at Weston on Wednesday.

The occupant of the home, a 49-year-old man who is allegedly a member of the Life and Death outlaw motorcycle group, was taken to hospital due to a medical episode.

During the search of the premises, police allegedly found a significant quantity of cannabis and declared a crime scene, before later executing a search warrant and seizing two rifles, a .22 calibre pistol, 350 rounds of ammunition, five gel blasters, an electronic stun device, almost 150 grams of methylamphetamine, 2kg of cannabis, $8300 cash, and other items.

Upon his release from hospital, the man was taken to Cessnock Police Station and charged with 33 counts, including supplying a prohibited drug, participating in a criminal group contributing to criminal activity, knowingly dealing with proceeds of crime, and 28 firearm-related offences.

He remains in custody and will face Cessnock Local Court on June 15.

Since Operation Hawk began, police have seized more than 80 firearms, 3300 rounds of ammunition, $2.8 million cash, and prohibited drugs with a combined estimated street value of more than $9 million.

Detective Superintendent Jason Weinstein said the operation followed the success of its predecessor, but with a renewed focus on regional areas.

"This week we've succeeded in demobilising a significant drug supply syndicate operating from Sydney's south-west, but also know the tentacles of illicit activity stretch far beyond our cities," he said.

"NSW attracts around 40 per cent of Australia's national organised crime population - many of whom attempt to evade the attention of police by operating outside of the Sydney metropolitan area.

"These arrests send a clear message to anyone involved in organised crime: that we are aware of your illicit activities and will hold you accountable irrespective of your location."
