You will need this authority if you intend to harvest kangaroos. Kangaroos can only then be harvested by holders of a class 13 or 14 Kangaroo Field Processors Permit.
This authority allows the holder to harvest on land other than (or in addition to) land owned by the holder, or by a member of the family or the employer of the holder, and entitles the holder to sell or use the carcasses of the kangaroos that have been harvested.
