Sylphie: not an issue as far as I can tell. I know people live in Ballarat, Geelong, etc. Even if you live in places like Berwick or Cranbourne you might only be 50kms from the airport but in peak hour you would have to allow 2 hours.
With our available days we have to be given 2 hours notice so if you live futher out you probably just sit around at home all day waiting for the call.
