No, the police dont monitor competition matches as such. They ask clubs for attendance sheets to make sure shooters are attending their range and shooting their 6 comps for the year (Primary club) and 4 shoots per year (each other club) The SSAA (governing body) here in Canberra wont hand in the iformation (so I have been told) as they believe it is a privacy issue. Sometimes when putting in for a permit to aquire, the registrar will demand a letter from your clubs stating you are conforming to the legislation, If you cant give them the letters of proof, you loose your guns.
The police arent standing behind you, ready to arrest you if you flinch (fortunately)
Actually, they have no right to be on or at the range unless called by someone, as the range belongs to the SSAA and is therefore private property.
