For the licence and other such fun and games. Look
here. In particular, you'll want the Certificate of Validation section. Note the timings and who you need to contact. The CAA being one of them. So that'll be the licence sorted out.
I threw some "best guess" details into the Australian Department of Immigration website and it suggests
these visas. You may wish to do this yourself to use the correct info.
This is the official "word from the horse's mouth" website and it is free to search.
So you'd be looking at March-April arrival? I would contact
Minovation for ideas etc. The CFI was a PPRuNer and she converted her UK CAA lic to Australian years ago. She'll have some ideas. They are based in Western Australia. I would consider flying up the WA coast line and have a play in the Kimberley. I used to work there. Incredible scenery and the worst of the Wet Season should be over. Come back via Alice Springs.
