If you plan to homestay in Australia for a while, you might like to buy a Prepaid Mobile phone. The cheapest new phones you can buy cost about $50, plus you have to buy about $20 of credit to start using the phone.
If you already have a Mobile Phone which works in Australia, you only need to buy a SIM Card (costs $2), plus about $20 of credit to start using the phone.
Ask us if you want to get a phone, and we'll help you with anything you need!
