The only DEM that I know about is the 9second product from Geoscience Australia - <a href="http://www.ga.gov.au/meta/ANZCW0703011541.html">http://www.ga.gov.au/meta/ANZCW0703011541.html</a> It does cost $100 and probably has some stringent use/distribution limitations.<br>
You want the DEM to produce a hillshade or to derive contours from? If you want contours the Geo Data 250k product (<a href="http://www.ga.gov.au/image_cache/GA8349.pdf">http://www.ga.gov.au/image_cache/GA8349.pdf</a>) is downloadable. Once again not certain on the licencing arrangements.<br>
