Looking to buy an Australian SIM card? There are about 50 operators in Australia - so much choice! However, not all of them are "easily accessible" to travelers (such as MVNOs focused solely on Australian residents - postpaid). Here is how to get an Australian SIM card as a tourist/traveler! In this video, I will introduce you to the Australian Main Operators (Telstra, Optus & Vodafone Australia/TPG Telecom) and the MVNOs (Mobile Virtual Network Operators), tell you why you can get both prepaid and SIM Only SIM cards in Australia, which Australian MVNOs are "easily accessible" to travelers and tourists, how much an Australian SIM card will cost you, tell you something about the Optus Traveller SIM (which is somewhat of a secret SIM card), the SIM card registration regulations in Australia, and whether you can even use your phone in Australia or not (frequencies - mostly European frequencies).
