It does not care about prices though. You will have to pay attention to that. If you are staying in Australia for a longer period of time you can avoid the expensive roaming costs. Just buy a prepaid card of the local providers. One advantage of doing it that way is that the complete costs for a so called StartUp-Kit (SIM-card and starting balance) can be used up fully making calls or texting. Starter-Packs of the three big providers, Telstra, Yes (Optus) and Vodafone, can usually be purchased at every post office, in various local stores of the providers or newspaper stands.
