The weekend operation by Strike Force Raptor coincided with a gathering of Rebels members and associates at its Dubbo clubhouse.
Officers issued two fines to the clubhouse for breaching its liquor licence conditions, and police say drunk gang members were stopped from entering local hotels.
Police raided the house of a 46 year old Dubbo man who was charged with possessing a prohibited weapon.
An alleged high ranking member of the Kiama Rebels was charged for breaching bail conditions, and police say a bikie was caught speeding more than 60 kilometres over the limit.
A car yard was also fined for failing to comply with licence conditions.
