Officers have issued firearm prohibition orders to 32 Rebels members in the past five days, including in Goulburn and the Far South Coast.
A NSW Police spokesman said the men included senior Rebel office bearers, members, nominees and associates of the Rebels, were all served with the orders by police from Strike Force Raptor.
The vast majority of the notices were issued to patched members of the gang, including a chapter vice president, two chapter presidents and a national sergeant at arms.
NSW Police Commissioner Andrew Scipione said crackdown follows new firearms and criminal groups laws, banning recipients from acquiring, possessing or using a firearm or ammunition.
“This law will help police rein in the use of firearms by criminals,” Commissioner Scipione said.
“People with a history of serious criminal activity or a violent past are well and truly in our sights. We no longer need a warrant to stop and search people who have been issued with a Firearm Prohibition Order"
He said officers acting in the interests of public safety could stop and search recipients of the orders, as well as their vehicles, homes and places of businesses.
Other locations includes suburban Sydney, Penrith and near Bathurst.
In total, 89 people in the state have been issued with Firearm Prohibition Orders.
Commissioner Scripione said more Firearm Prohibition Orders would be issued in the coming weeks.
“Over the last five days, the Rebels – the nation’s largest outlaw motorcycle gang – have been our focus,” Commissioner Scipione said.
“However, let me be clear: a number of other people will be served with Firearm Prohibition Orders over the remainder of this month and throughout the summer,” Commissioner Scipione said.
