Two Rocks Commonwealth Marine Reserve
IMPORTANT INFORMATION FOR MARINE USERS – TRANSITIONAL ARRANGEMENTS
The Commonwealth marine reserves declared in November 2012 are under transitional
arrangements until management plans come into effect in July 2014. Transitional
arrangements involve NO CHANGES ON THE WATER for marine users. 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.
