For those who have had a firearms prohibition order served against them, it makes it a crime for them to access firearms or to visit places with guns. It also makes it an offence to knowingly supply someone with a gun, knowing that they have a firearms prohibition notice against them, and it provides the police with warrantless search powers so that they can practically enforce this law by searching for guns where they believe they are on premises where there's someone with a firearms prohibition order against them.
