Is Australia cheaper than the UK?

Yes, most things are a little bit cheaper in Oz. In general, you will pay roughly the same amount for a beer as you would in the UK but most other things like food and clothes are cheaper. It can all depend on where you are though. For example, a packet of crisps and a bottle of water are going to cost you twice as much at an outback roadhouse/petrol station than they would at a Melbourne corner shop. Adventure activities are reasonably priced and there are plenty of backpacker offers to be taken advantage of.
