Unlimited Talk & Text and 5GB Data with Red Bull Mobile ($365)

This is probably the cheapest unlimited mobile plan you can hope to get in Australia. Red Bull Mobile has a plans for all pockets. The minimum plans start at $20. If you are looking for a better deal, you should consider the 365 access. It allows you to pay $365 for a year, ($1 a day) and get access to unlimited calls and text throughout the entire year. On top of that you get extra 3 months for free. The handset that comes with this offer is the HTC Explorer. If you know any deal that is cheaper that this one, go for it. We don't think you will find any better deal anyway.
