GDAL Results Interpret for Australian Raster

[Nick Dabner]

Hello all,

I have a rasterset covering parts of Australia. TatukGis and other
products can view it, but I cannot even get it to simply display in
mapserver - usually just a blank screen. Furthermore, the information
provided by gdalinfo with respect to the datum is unknown, so I am not
sure if a projection is required etc.

Can anyone suggest the portions of the mapfile which would allow this
raster to load? I have included most of gdalinfo details below, TIA:
