The situation in Australia is quite remarkable compared to many other countries around the world.
If you have read my Buying a SIM Card in Australia Guide, then you know that Australia has over 50 Mobile Virtual Network Operators (MVNOs), whereof around 20 of them offer prepaid services.
Each of these main operators have their pros and cons. So does choosing an MVNO over a Main Operator and vice versa.
Because there is so much choice in Australia, I have grouped the Australian SIM card reviews by their Main Operators for easier comparison. Click on any of the logos or links to read my review of the said operator.
I have also made several comparison articles, like operator-bound MVNO comparisons. They will be listed as well.
