So another one of the essential things that you are going to need when getting to Australia is an Australian sim card and telephone number. Your going to need this to be able to call up about jobs, apartment viewings, buying a car and all the other things like when you meet someone new and want to contact them. Once again there are a lot of options in regards to sim card providers and the deals they offer but I will run through the main ones and there benefits. Most of you will bring a phone from home which if you do, make sure its UNLOCKED or else you'll have to pay to get it unlocked which could end up costing you a lot and wasting a lot of your time. If your planning on buying a phone when you get to Australia, then you can pick up a cheap phone which allows Facebook, apps, twitter, calls, messages all the basics for about $80. You could also get a contract but I would recommended just getting a PAYG deal as you never know what your going to be doing or when your going to be leaving the country so could end up wasting a lot of money. Whereas if you get a PAYG deal you just top up so much each month and it gives certain amounts of data, calls and messages.
