South-west Corner Commonwealth Marine Reserve

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.

  • Six key ecological features:
    • Albany Canyon group (high productivity, feeding aggregations)
    • Cape Mentelle upwelling (high productivity)
    • Diamantina Fracture Zone (unique sea-floor feature likely to support deepwater communities characterised by high species diversity and endemism)
    • Naturaliste Plateau (unique sea-floor feature, likely to support deepwater communities characterised by high species diversity and endemism)
    • western rock lobster habitat (species with an important ecological role)
    • Commonwealth marine environment surrounding the Recherche Archipelago (high biodiversity, breeding and resting aggregations, including the most extensive areas of reef on the shelf within the South-west Marine Region)
  • Representation of the Donnelly Banks, east of Augusta, characterised by higher productivity and including nursery habitats
