The Bureau of Mineral Resources, Geology and Geophysics (BMR) conducted a seismic survey in the Denison Trough, in the western part of the Bowen Basin in Queensland in 1979. The survey continued work commenced in 1978 aimed at delineating the configuration of the trough and providing stratigraphic information from the Permian sequence which, in conjunction with current Geological Survey of Queensland stratigraphic studies, would enable reliable stratigraphic correlations to be made throughout the trough. The survey obtained 265 km of digitally recorded mainly six-fold Common-Depth-Point seismic reflection data.

An optimal combination of geological, geomorphological and climatic properties, along with its high level of contemporary seismicity, makes the Archean craton in the SW corner of Australia an excellent natural laboratory for studying earthquake behaviour in stable continental regions (SCR). Analysis of the palaeo-seismic data derived from 35+ palaeo-earthquake scarps suggests that the long-term seismicity rate is a tenth of the contemporary rate. A 50 site regional GPS/Geodetic network was occupied over the 200 x 400 km study area in 2002 and 2006. Analysis of this data suggests that the long term tectonic strain-rate is about a one seventh (with an uncertainty range of half to a hundredth) of the rate derived from the seismicity recorded over the past 60 years. Re-occupation of this network in 2012 and reprocessing of the 2002 and 2006 data, using updated techniques, should reduce the uncertainty range. The difference between the contemporary seismicity and that suggested by the geological and geodetic data is strong evidence for an episodic (or non-stationary) model of seismicity in non-extended cratonic SCC. By contrast, the Mt Lofty/Flinders Ranges region in South Australia may be exhibiting stationary seismicity behaviour. The geologic structure of this region originally formed in an extensional setting in the Precambrian, and was reactivated in compression in the Cambrian (ca. 500 Ma.) and under the current the current stress field (since ~10-5 ma.). A 50 site GPS/Geodetic network was established in the Flinders ranges in 2003 and reoccupied in 2012. The strain-rate estimated from this data is expected to answer the key question of: Whether the geodetic strain-rate is consistent with the contemporary seismicity (and palaeo-seismicity) in this region or not. Consistency would suggest that the seismicity in this non-extended SCR is stationary, and should be described by a different seismo-tectonic model than the non-extended cratonic SCR

The offshore seismic data consists of field, processed, and seismic navigation data. Reports of the acquisition, processing and interpretation reports plus reprocessed seismic data and reports are also held. The collection is derived from the submission of seismic data under the Offshore Petroleum and Greenhouse Gas Storage Act and previous legislation. The Petroleum (Submerged Lands), the Offshore Petroleum, and the Offshore Petroleum and Greenhouse Gas Storage Act 2006 (OPGGSA) requires petroleum data to be submitted to the State Designated Authority (DA). The Act(s) also require the DAs to make copies of the data available to the Commonwealth Minister through the Joint Authority.

These data are the time series seismograph, hydroacoustic and infrasound data recorded from Australian National Seismograph Network (ANSN) observatories in Australia, islands in the Pacific, Southern and Indian Ocean's and the Australian Antarctic Territory. ANSN observatories include facilities operated by Geoscience Australia in collaboration with other international agencies. These data are acquired for the purpose of the detection and location of earthquakes and tsunamigenic events within the Australian continent and its surrounds. The dataset is also used to meet a subset of Australia's obligations to the Comprehensive Nuclear-Test-Ban Treaty Organisation (CTBTO) to fulfil Australia's commitment to nuclear explosion monitoring. The seismic waveform data records seismic events to allow for the detection, location estimation (position and depth) and magnitude of earthquakes of magnitude of 3.0 or greater anywhere in Australia.
