Geothermal Energy Resources in Australia

Geothermal Resources Map

Temperature at a depth of 5 km in Australia. Contours 75, 100, 125, 150, 175, and 200oC. Redrawn from Cawood (1996), after Doone Wyborn and Prame Chopra of AGSO. Reproduced courtesy of Australian Geographic.

>> Status of the Geothermal Industry in Austrlia




One cubic kilometre of hot granite at 250 degrees centigrade has the stored energy equivalent of 40 million barrels of oil. Australia has large volumes of identified high heat production granites within 3 to 5km from the surface. This represents a vast resource of clean energy that can potentially be tapped by hot dry rock geothermal technology.

The map shows areas in Australia where estimated temperatures at 5km depth are above 225oC. It is the result of a study of thousands of existing exploration wells (mostly oil and gas) by two of Geodynamics' directors (Wyborn and Chopra) for the Energy Research and Development Corporation.

Two states in Australia (New South Wales and South Australia) have adapted their mineral legislation to enable the granting of HDR geothermal exploration licences. Geodynamics has secured two HDR geothermal tenements in the Hunter Valley in New South Wales and two in the Cooper Basin, in South Australia.

Geothermal temperatures in Victoria

Sub-surface temperatures at 500m


Sub-surface temperature at 500m below ground level (C°)

The above map shows the temperature below the surface at 500m depth. This resource assessment was developed in partnership with Sinclair Knight Merz and Professor Jim Cull, Monash Geoscope.

Victoria has limited Hot Dry Rock resources which are at depths that may currently preclude commercial energy generation. The hydrothermal property of geothermal bores in Victoria has potential for geothermal direct use applications.

Geothermal temperatures in Victoria increase on average between 3 and 4ºC per 100 metres from the surface. Whilst Australia has great potential for developments in the use of Hot Dry Rocks for energy generation, Victoria has limited Hot Dry Rock resources. The feature of the geothermal systems in Victoria of most interest is the highly productive aquifers in the unconsolidated basin sediments at depths of up to 1000 metres.
These aquifers provide uniformly high productive geothermal bores.

Applications that take advantage of the geothermal resources in Victoria can be found in the form of geothermal heat pumps, space heating and district heating, bathing and swimming pool heating, aquaculture pond heating, greenhouse heating, industrial uses, cooling and air conditioning, and agricultural drying.

Potential resources of hot dry rocks in south-west Queensland

Queensland contains large potential resources of hot dry rocks, particularly in south-west Queensland beneath the Eromanga Basin. Legislation to enable these resources to be explored and developed is expected to be passed in 2004.
