The powers that be have released new and allegedly better ASTER DEMs - Digital Elevation Maps - of the world.
www.gdem.aster.ersdac.or.jp
Unfortunately Australia and regions outside of the USofA have been down sampled to 3 arc-sec (90 metre) from the original 30m and 15m data. ASTER and SRTMv2 thus are at the same resolution - 1 "pixel" is 90m^2.
A small preview of the data can be found here on Air-Stream...

I have saved some images using both data sets of the Magill/Mt Lofty region visualized with 3DEM.
The "dimple" in the lower left of the SRTMv2 image is Thornton Reservoir and the high ridge running up to Mt Lofty upper right.
