TCO2 fluxes and pools for sediments in Jervis Bay, NSW (June and August 2008 and February 2009)

Geoscience Australia carried out marine surveys in Jervis Bay (NSW) in 2007, 2008 and 2009 (GA303, GA305, GA309, GA312) to map seabed bathymetry and characterise benthic environments through colocated sampling of surface sediments (for textural and biogeochemical analysis) and infauna, observation of benthic habitats using underwater towed video and stills photography, and measurement of ocean tides and wavegenerated currents. Data and samples were acquired using the MV Kimbla. Bathymetric mapping, sampling and tide/wave measurement were concentrated in a 3x5 km survey grid (named Darling Road Grid, DRG) within the southern part of the Jervis Bay, incorporating the bay entrance. Additional sampling and stills photography plus bathymetric mapping along transits was undertaken at representative habitat types outside the DRG. 

This 126 sample data set comprises TCO2 flux and pool data for surface seabed sediments (~0 to 2 cm).

AusBathyTopo (Australia) 250m 2024 - A national-scale depth model (20240011C)

The AusBathyTopo 250m (Australia) 2024 Grid is a national-scale depth model for Australia that replaces the AusBathyTopo 250m (Australia) 2023 Grid.



This publication is the result of a collaborative partnership between Geoscience Australia, the Australian Hydrographic Office, James Cook University, and the University of Sydney. It has been compiled using 1456 unique data sources from multibeam echosounders, single-beam echosounders, LiDAR, 3D seismic first returns, Electronic Navigation Charts and satellite derived bathymetry alongside higher-resolution regional compilations. In particular, the map incorporates new innovations such as the use of earth observation data (satellite based) produced by Digital Earth Australia to improve shallow coastal depth modelling to present a seamless transition between land and sea. All source bathymetry data were extensively edited as 3D point clouds to remove noise, given a consistent WGS84 horizontal datum, and where possible, an approximate MSL vertical datum. This new continental-scale grid represents decades of data collection, analysis, investment and collaboration from Australia’s seabed mapping community and is a significant improvement on the 2009 and 2023 compilations.



The data extends across a vast area from 92°E to 172° E and 8°S to 60° S. This includes areas adjacent to the Australian continent and Tasmania, and surrounding Macquarie Island and the Australian Territories of Norfolk Island, Christmas Island, and Cocos (Keeling) Islands. Australia's marine jurisdiction offshore from the territory of Heard and McDonald Islands and the Australian Antarctic Territory are not included.

AusSeabed Bathymetry Compilations Coverage Database

The AusSeabed Bathymetry Compilations Coverage Database contains polygon extents of bathymetry data acquisitions along with identifying attributes and contact details where the data is not held by Geoscience Australia.  It is an important scientific resource that identifies data spanning coastal, continental shelf and deep sea locations. 



This dataset is live and will continue to be augmented as coverage details are supplied from AusSeabed collaborators who wish to share their knowledge of data availability to the broader marine community. The database is updated regularly and is made available via the AusSeabed Marine Data Portal using OGC compliant web services. Compilations have been generated from one or more Survey/Data Acquisitions by a wide range of organisations and countries, both inside and outside Australia's marine jurisdiction, using multiple systems and for various applications. Compilation coverages are published where the polygon extents intersects with Australia's marine jurisdiction, including the Australian Antarctic Territory.  Each polygon in the layer contains metadata describing compilation details. 

Note that polygons may not be representative of the true survey extent due to the data gridding process.

Digital Earth Australia (DEA): From Satellites to Services Poster

The Australian Government is investing in a world first analysis platform for satellite imagery and other Earth observations.

From sustainably managing the environment to developing resources and optimising our agricultural potential, Australia must overcome a number of challenges to meet the needs of our growing population.

Digital Earth Australia (DEA) will deliver a unique capability to process, interrogate, and present Earth observation satellite data in response to these issues. It will track changes across Australia in unprecedented detail, identifying soil and coastal erosion, crop growth, water quality, and changes to cities and regions.

DEA will build on the globally recognised innovation, the Australian Geoscience Data Cube1; which was the winner of the 2016 Content Platform of the Year at the Geospatial World Leadership Awards and was developed as a partnership between GA, CSIRO and the National Collaborative Research Infrastructure Strategy (NCRIS) supported National Computational Infrastructure (NCI).

The electrical lithosphere of the Australian continent

We present a novel 3-D electrical resistivity model of the sub-continental Australian lithosphere. The model was obtained by inverting the magnetotelluric responses from the Australian Lithospheric Architecture Magnetotelluric project (AusLAMP) array and the legacy geomagnetic responses from the Australia-wide Array of Geomagnetic Stations (AWAGS) array. We use a novel distributed 3-D electromagnetic inverse solver GoFEM that supports multi-scale and locally refined meshes and performs 3-D inversion directly in the spherical frame, thereby avoiding any potential distortions related to geographic projections and accounting for spherical effects. Thanks to these methodological advances, we can image the coherent crustal and lithospheric anomalies across scales, which exhibit correlations with major tectonic units, and unlock new insights into the crust-mantle controls on the occurrence of major mineral resources.

Tectonic geomorphology and Holocene uplift rates of the Lae Urban Area, Papua New Guinea

Lae is Papua New Guinea’s (PNG’s) second largest city and is the home of PNG’s largest port. Here, a convergence rate of ~50 mm/yr between the South Bismarck Plate and the Australian Plate is accommodated across the Ramu-Markham Fault Zone (RMFZ). The active structures of the RMFZ bifurcate immediately west of the Lae urban area, with one trace (the Wongat South Thrust) trending southeast through Lae City and connecting to the Markham Trench within the Huon Gulf. The geomorphology of the Lae urban area relates to the interaction between riverine (and limited marine) deposition and erosion, and range-building over the Wongat South Thrust. Flights of deformed river terraces imply repeated tectonic uplift events. Terrace riser heights are typically on the order of 2.5-3.0 m, indicating causative earthquake events of greater than magnitude 7.0. Preliminary dating of fluvial and marine terrace deposits indicates a recurrence for these events in the order of 300-400 years, at an uplift rate of ~12 m/kyr. The results of the tectonic geomorphology study form part of a PNGAus partnership project, and will inform future seismic hazard and risk assessments for the region

Australia's Antimony Supply Chain

Australia's Antimony Supply Chain is a national snapshot of the antimony sector as of January 2026 including production, resources and exploration.



Antimony is a critical mineral essential for energy, defence and advanced manufacturing applications. While its traditional demand has come from flame retardants and lead‑acid batteries, consumption in these legacy sectors is declining due to material substitution, modern alloying practices, and the shift to lithium-ion batteries. Increasing recycling rates are meeting most metallurgical demand (e.g. lead-acid batteries), meaning primary supply growth is now tied largely to non-metallurgical, technology-driven uses. Antimony use in solar photovoltaic glass has expanded rapidly, and it continues to play an important role in electronics and certain semiconductor applications. Strategic applications include use in ammunition.

Beneath the surface: unlocking the Adavale Basin in south-central Queensland with stratigraphic drilling and integrated geoscience datasets

Geoscience Australia, through the Data Driven Discoveries (DDD) Program and the Resourcing Australia’s Prosperity initiative, has acquired precompetitive geoscience data to enhance understanding of the Adavale Basin’s subsurface geology. These initiatives have integrated deep drilling, new seismic imaging and airborne geophysics with legacy data and information into a comprehensive, multi-scale dataset. In November 2025, the program completed the Adavale Basin stratigraphic drilling project, with the deep stratigraphic borehole, GA&nbsp;Enniskillen&nbsp;1, reaching a total depth of 3,023&nbsp;m. GA&nbsp;Enniskillen&nbsp;1 penetrated the Eromanga, Galilee and Adavale basins and collected rock chips, 976&nbsp;m of continuous core and groundwater samples. These data contribute to refining stratigraphic and depositional models and improving insights into hydrogeological connectivity. A new deep-crustal seismic survey, integrated with reprocessed legacy data, refines basin architecture and structural complexity, while new airborne electromagnetic and gravity gradiometry datasets enhance mapping of aquifers, evaporites, and structural features. Initial findings reveal salt deposits localised near faulted margins rather than basin depocentres, challenging conventional halite models and highlighting the variable character of Australian salt systems. This work underscores the need for tailored strategies in structurally complex basins and shows how integrated geoscience reduces risk for resource exploration.

Getting the rocks right

The Australian Stratigraphic Units Database (ASUD) indexes geological publications to provide a current picture of Australian stratigraphy including lithology, age and unit relationships. The ASUD promotes usage of correct and current stratigraphic terminology to facilitate effective communication related to Australian geological units and improve the quality of geoscience publications.

This poster demonstrates how to access the data and supporting tools in addition to demonstrating the critical role that the ASUD plays with respect to rigorously linking Geoscience Australia’s sample-based datasets (e.g. geochemistry, geochronology) to geology in GIS products (such as Geoscience Australia’s Layered Geology) to generate mineral potential assessment maps.
