Image showing gravity sation coverage and relative reliability over Australia, updated to May 2011

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.

Australia is not on the edge of a tectonic plate so why do we have earthquakes? The Indian-Australian plate is being pushed north and is colliding with the Eurasian, Philippine and Pacific plates. This causes stresses to build up in the interior of the plate which is released during earthquakes.

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 (This chart is now superseded.)

The purposes of this Bulletin are to explain and describe the accompanying 1:10 000 000-scale geological map, to discuss briefly the map's units, and to provide readers and users with a guide to the rapidly expanding literature of Antarctic geology, from which they can obtain more detailed information.

1:10 million scale map of operating mines in Australia

Map showing Australian nickel resources

Map shows lead and zinc resources of Australia.

This map shows operating mines and deposits where development has commenced or a decision to mine has been announced. It illustrates the geographic distribution of mines and the range of commodities mined.
