Does anyone know if Australian topo map GeoTIFFs are made available anywhere (preferably for free)?
LINZ makes them available in New Zealand – http://www.linz.govt.nz/topography/topo-maps/index.aspx, and I was hoping a similar service was available for Australia.
Carta topográfica escala 1:50 000
Three major scales are available: 1:1,000,000; 1:250,000 and 1:50,000.
The DRG maps in the scale of 1:50,000 are being issued and as of today (August 2008) about 85% of the country is available.. They have the same format characteristics as the 1:250,000 ones.
The 1:50,000 maps have shading to help in the terrain contour interpretation.
There are vector versions of these maps on both the 1:50,000 and 1:250,000 scales. For the 1:50,000 they are available for 60% of the country and for the 1:250,000 the whole territory is available.
The vertical divisions numbered 11 to 16 are the UTM zones in which Mexico lies.

Try data.gov.au for Australian spatial data. Most of it in kml/kmz format.
Most state governments also have equivalent sites. For example:
Geoscience Australia has an extensive catalogue of data for sale or for free download, including the Geodata 250K Topography dataset package. Also, the Bureau of Statistics now offers a lot of data (including historical) in spatial formats.
A few of these sites will require a sign-up, but beyond a basic form to fill in you should be good to go with the data.

MapConnect has 1:250k data for download in many formats, including as ECW rasters which can be converted to GeoTiff with GDAL if needed. They also have a partial coverage of 1:50k topographic maps, but they cost money.
If you're interested in creating your own topographic maps, check out TopOSM, which aims to produce high-quality topographic maps from open data, and includes the source code to do so if you're willing to get your hands dirty. You might also find some hints in this quesion.
