There is a better one available from AGSO, based on gridding up the gravity
stations.  Last week I visited AGSO (the geological survey) and had a
meeting with
the person who is producing the new DEM - it is based on the gravity
stations suplemented by all the spot heights from the national mapping, and
gridded using Hutchinson's algorithm - it will be at about ? 3 arc-seconds
resolution (from memory).  However, the agencies involved (AGSO and AUSLIG)
have a cost recovery requirement imposed by the federal government, so when
this becomes available it will cost real $$.  Not their choice, so no flames.

 You guys in the US probably don't realise how lucky you are with the US
policy of cost-of-reproduction.  I am involved in several cooperative
projects with the peopls who are custodians of various datasets, and even I
have to sign contracts, non-transfer/disclosure agreements, etc, and they
get a $ credit for any data that I use.

SO, for the moment, etopo5 is about all that is available.
