Abiotic surrogates for marine biodiversity have been identified across multiple ecosystems and vary according to spatial scale, region, habitat, and biodiversity measures. Compared to other regions, our knowledge of the relationships between abiotic and biotic factors in northern Australian waters is limited. As part of the Australian Government's program of collecting pre-competitive regional information on seabed habitats, Geoscience Australia recently collaborated with the Australian Institute of Marine Science to conduct a survey along a representative channel of the Van Diemen Rise in the Joseph Bonaparte Gulf (50 - 250 km off the coast of Darwin). We used a range of methods to collect physical and biological data including multibeam sonar, towed underwater video, oceanographic moorings, sediment sampling, and epibenthic sampling. Depth was a major driver in epibenthic biomass and richness. Sponge and octocoral gardens were common on almost all banks surveyed but rarely found on other geomorphic features, suggesting that biodiversity of epifauna is linked to geomorphology and depth. Infaunal assemblages were extremely diverse in soft sediment plains and correlated to some geochemical factors. Species-level identifications will show whether these biological communities are different across sites and thereby reveal potentially unique habitats in the region. Results from this survey will identify key environmental drivers of biological assemblages in a representative region of the Van Diemen Rise to produce regional-scale information on seabed habitats in northern Australia for resource management purposes.

The Curnamona Province in eastern South Australia is host to significant mineral and energy resources, including U, Cu-Au and geothermal. The Province is largely buried beneath recent sediments, with outcrop restricted to the Olary and Broken Hill Domains in the south, and the Mount Painter region in the north. In order to understand the subsurface geology in the Curnamona Province, several deep crustal seismic reflection surveys have been undertaken. Most recently, the 08GA-C1 seismic line was acquired as part of Geoscience Australia's Onshore Energy Security Program. This line extends from the previously acquired 03GA-CU1 line in the south, and runs north to the Mount Painter area through the Benagerie Ridge. The prevalence of recent sediments in the area covered by the seismic line renders it difficult to constrain the geology imaged by the seismic data. To assist in meaningful interpretation of the data, several drill holes in the vicinity of the seismic line have been investigated. These are distributed from the north of the line to outcrop in the south, and intersect sedimentary and igneous rocks. Geochemical, geochronological and petrographic analysis has been performed on the samples taken. The results of these are documented in this report.

The Onshore Energy Security Program, funded by the Australian Government and conducted by Geoscience Australia, has acquired deep seismic reflection data across several frontier sedimentary basins to stimulate petroleum exploration in onshore Australia. Interpretation of the new seismic data from these onshore basins, focusing on overall basin geometry, internal sequence stratigraphy and petroleum potential, will be presented here. This will provide the basis for ongoing work which will aim to assess the petroleum potential of these basins. Key words: Seismic data, Arrowie Basin, Millungera Basin, Georgina Basin, Yathong Trough, Darling Basin.

On shaky ground? Understanding earthquake ground-shaking in Australia New prediction equations and Australias first site-response model to aid earthquake disaster planning The devastating 1989 Newcastle earthquake, which claimed 13 lives and caused over $800 million in insured losses, showed that Australian communities are not immune to the effects of earthquakes. New ground-motion prediction equations integrated with the first site-response model for Australia can refine our estimates of earthquake ground-shaking, providing the potential to rapidly assess earthquake impact for disaster response.

This dataset reflects the external boundaries of all native title determination and compensation applications that are currently recognized and active within the Federal Court process. Applications that are non-active (i.e. withdrawn, dismissed, finalised, rejected or combined) are only included as aspatial records for completeness. This is a national dataset with data partitioned by jurisdiction (State), for ease of use. Applications stored for each jurisdiction dataset include applications which overlap into adjoining jurisdictions as well as applications which overlap with these for completeness. This dataset depicts the spatial definition of active Claimant and Non-claimant native title determination applications and compensation applications. Where possible these may include internal boundaries or areas excluded. Aspatial attribution includes National Native Title Tribunal number, Federal Court number, application status and the names of both the NNTT Case Manager and Lead Member where assigned to the application. Applications included on the Schedule of Native Title (Federal Court) include all registered and unregistered applications as well as determined applications that are yet to be finalized. Geospatial data portraying native title information produced by the National Native Title Tribunal may not be on-sold. Value added products using this data must acknowledge the National Native Title Tribunal as the data source and include the NNTT disclaimer.

This dataset attempts to reflect the boundaries of claimant applications for Native Title as per the Register of Native Title Claims (s185, Native Title Act; Commonwealth). This is a national dataset but data is stored by jurisdiction (State), for ease of use. Applications stored for each jurisdiction dataset include applications which overlap into adjoining jurisdictions as well as applications which overlap with these. This dataset depicts the spatial record of registered claimant applications. Aspatial attribution includes National Native Title Tribunal number, Federal Court number, application status and the names of both the NNTT Case Manager and Lead Member assigned to the application. Applicants of registered applications have the Right To Negotiate (RTN) with respect to certain types of Future Acts over the area being claimed. Whilst applications that are determined are recorded on a separate register, all registered applications remain on the Register of Native Title Claims until otherwise finalised.
