For example, if you buy a Mentari Bali sim card, use the 01017 prefix before the Australian banks nunber and it costs you about 20c per minute (or thereabouts).
I also think you can probably email your bank.
To be saffe, I would contact the bank in Australia and give them the facts then deal with it once you get home.
