Recreative flying in Australia

[CHCH]

Hi there,

Beginning of next year I'm going to Australia and New-Zealand for 2 months. Now I plan to fly as well over there. Some questions;

- What do I need to do to convert my licence (I have a CPL (SE+ME+type B747-400))?
- What is the most interesting region to fly in (it's my first time going there)?
- What are the average costs of hiring a C172, Piper,....?

All other information is highly appreciated!

Thanks, CHCH
