Been road tripping off Melbourne and i would like to warn you guys: don't use Vodafone AU ... use either Optus or Telstra.
Along great ocean road my voda has given me 100% grief: no reception in buildings, poor reception everywhere, no reception many places ... and my wife's optus - 100% usability on high speed 3G! aarrrrgh
Note: VFAU "roams" on telstra network when VFAU does not have coverage - but i think because the places we've been "have" VF coverage (albeit atrocious), I can't latch on to telstra in these places
