I tried that. I found that my Telstra modem was "locked" so I couldn't use it. I was able to get a pin number ( unlock key) but then all the software screwed up on my PC. I needed to download new modem software but couldn't connect!
I ended up using wifi.
Did you have yours unlocked before you left Australia?
