With the strong interest in Australia's mining and its geology, potential investors and the public can now access newly developed digital data on the surface geology of the country's eastern States.

The information provides a clear, updated picture of rock types and other surface material in Queensland, New South Wales, Victoria and Tasmania to help scientists and the public develop a greater understanding of the geological make up of regolith in the four States.

The new, seamless data is the second edition on surface geology for Queensland and New South Wales and the third edition for both Victoria and Tasmania and is part of a project to improve the potential for economic, social and environmental benefits through delivery of the continent's surface geology in seamless, digital format.

The new editions provide a more consistent portrayal of regolith material and a uniform coding system for all four States. The data also contain more extensive descriptions of geological types and incorporate recent mapping in Queensland, New South Wales and Victoria. In addition, it has edgematching to align with information released last year on the Northern Territory and a soon-to-be-released South Australian dataset.

Individual State 1:1 000 000 scale datasets are available as a free download.
