The Earthquake hazard map of Australia 1991 was prepared by members of the Standards Australia Working Group BD/6/4/1 based on the hazard analysis of Gaull, Michael-Leiba and Rynn (1990). Reference: Probabilistic earthquake risk maps of Australia, Australian Journal of Earth Sciences,37, 169-187.

This map shows the area of the Automatic Longline 183m Depth Closure within the Commonwealth Scalefish Hook Sector (also known as the Gillnet, Hook and Trap Fishery (GHAT)) of the Southern and Eastern Scalefish and Shark Fishery. Modified from GeoCat 68490 (2008) as per the Southern and Eastern Scalefish and Shark Fishery (Closures) Direction No. 1 2009 - Schedule 15. Produced for the Australian Fisheries Management Authority. Not for public sale or distribution by GA.

Geoscience Australia distributes a range of Antarctica maps and images at various scales and currency, on behalf of Australian Antarctic Division. These products are very diverse and include topographic maps and satellite images, ranging from landscape specific (1:1,000 scale) to regional (1:20,000,000) scale.

The Australia Epoch 1995.0 geomagnetic field chart maps the main geomagnetic field and its secular variation in the Australian region between 1995 and 2000 . The chart is derived from the Australian Geomagnetic Reference Field model (AGRF) of the same epoch. From 1990 to 2005 the AGRF has been updated at five yearly epochs. A main field model is produced for each five yearly epoch, along with a prospective secular variation model to extend the life of the model. The AGRF model represents the Earth's main magnetic field originating from the core and the broad scale crustal field. The AGRF does not model short term variations of the magnetic field with time, such as those caused by solar activity or ionspheric currents. The AGRF is derived from vector magnetic data from ground level, aircraft and satellite surveys as well as the network of geomagnetic observatories and repeat stations run by Geoscience Australia and neighbouring countries.
