My best friend just moved to Oz this week. I bought a Truphone SIM for Oz. I considered by a local one down there, but decided that it was a good enough deal and easy to keep alive from outside the country. After a great deal of experience with UK Mobile market, I was very underwhelmed by the Australian market where connection charges were the norm. They soften the blow with a number of flat rate talk deals which let you talk for one minute or twenty minutes for the same price. The problem is that too many of my calls are in the one to two minute range.
