The wonderful map is Geoscience Australia's: Australia's Maritime Zones Edition 3 © Commonwealth of Australia (GeoGat 63690), it retails for $22.00 with a postage cost of $9.21.
The map (Edtion 3) has been used to indicate new State maritime implications in relation to Australia's Continental Shelf Limits. A new edition is in production and is in the review stage. All this work done by Geoscience Australia in Edition 3 is currently being updated to reflect the May 2012 Proclamation of the Australian Continental Shelf Limits. So please be aware that the map no longer reflects current Continental Shelf Limit arrangements; but it will be close enough for our point to be clearly made visually.
