Free maps for
Australia ( I haven;'t used this site for ages so hopefully it all still works the same)
http://www.ga.gov.auunder the online tools column (just left of centre) there is a map
connect (make your own topo maps)
this will lead you to a page where you have to agree to their
conditions -Agree and then hit submit
you will end up with a map of Aus that you can zoom in/out and will
show the 1:250k sheets
click on the 11th tool from the left in the toolbar (the mapsheet
tool) on the right of your screen make sure ecw-raster is selected.
Select and add maps sheets (you can only select 5 at a time)
Show/confirm your order you will then have to confirm license (if you
haven't been to the site before there may be an extra step around
here - not sure) you will then need to complete the registration and
fill in the license agreement (sounds a lot but will only take around
30 seconds). Continue to download, this will generate an email back
to you with the link for the actual download from
