Overview

IMPORTANT INFORMATION FOR MARINE USERS

Transitional arrangements

Until a management plan comes into effect transitional arrangements apply.

  • Under the transitional arrangements, there are NO CHANGES ON THE WATER for users of new areas added to the Commonwealth marine reserves estate.
  • NOTE: There are no changes to management arrangements in the marine reserves that existed prior to the establishment of the new reserves, that is, the same restrictions on activities will continue to apply even where those reserves have been incorporated into new reserves.
