The purpose of the mapping was for use in assessments to identify potential locations for marine protected areas in NSW. For more information see: Breen D.A. and R.P. Avery. (2002).

Copies of the report may be borrowed from the library: Environment Australia, GPO Box 787, Canberra ACT 2601 Australia This coverage is intended for used in regional level marine conservation assessment. It was prepared using very low cost techniques (ie. unrectified API) and should not be relied upon for navigation purposes. THIS DATA IS NOT SUITABLE FOR NAVIGATION PURPOSES.
