GPSdrive will do it I think. Apparently able to download appropriate
maps by itself from maps.google
Unfortunately, the only maps available for Australia appear to be
by Senseless (or something that sounds similar and means the same
thing). TomTom maps for Australia cost 200 Euros. You can get all of
Europe from TomTom for about 60 Euros.
Germany/Austria/Switzerland plus other major European roads, on
mini-SD (with SD adapter) + genuine TomTom GPS bluetooth set me back
140 Euros from a retailer (in Germany) via eBay.
I could "upgrade" to include Australian maps but there doesn't seem
to be much point. Nobody looks as though they know where they're
driving in Australia!

I have Cetus GPS on my Treo for track-logging from GPS. Haven't yet
gotten to downloading to Linux and mapping.
I understand that the tracklogs can be "replayed" into GPSdrive once
extraced from the CetusGPS log databases. There's free software with
CetusGPS to do it and the main app is also open source. Just to keep
this on-topic! :-)
