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.

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. (This chart is now superseded.)

This map shows Australian operating mines, deposits where development has commenced or where a decision to mine has been announced, and selected mineral deposits. Closed mines or mines not currently operating are not shown. It illustrates broadly the geographic distribution of mines and deposits a the range of selected commodities mined.
