Contact Telstra and ask them to put you on International Roaming. You only ever have to do this once with them so the next time you travel overseas your phone will automatically roam to local phone company. But we warned if people phone you will pay for the call. Not sure how prepaid cards/accounts work but I'm sure a fellow forumite will come up the answer for you.
