The main thing after your arrival will be to find a place to sleep and many choose some sort of temporary accommodation for the first few days or weeks. Unless you can stay at a friend's place or have already found a place to stay for longer, you should book accommodation for the first few days ahead. Depending on your needs and budget, that can be a hotel, an apartment or a cabin on a campground! Choose a convenient location as it will be the base from where to find your home, organise a car, buy an Australian SIM Card and all the other things which will help you get settled in those first few days.
