Airspace Act 2007. Airspace is administered by CASA and therefore desert jurisdiction. States can only stipulate law or direction at other than federal airports within their state.
Aircraft are note state registered, they are Australian registered. Federal. A pilot license is federal not state.
It is interesting how any requirements can be stipulated when overflight per se does not affect the environment being overflown. Departure and arrival protocols at federal airports are federal jurisdiction. Except where agreement is reached landside for local (state) law enforcement powers.
