The marine farming industry is regulated by the Department of Primary Industries, Parks, Water and Environment (DPIPWE) under the Living Marine Resources Management Act 1995 and the Marine Farming Planning Act 1995.

Marine Farming leases are generally marked at their extremities by special marks. These markers are yellow in colour and may have lights and a cross.

Mariners should try to avoid navigating within the lease, as there may be underwater hazards that are not charted or easily apparent when navigating in the vicinity.

The location of marine farm leases and corner marks can be found on the MAST GIS.
