Hi Zac.
I'd suggest you find some reasonably inexpensive gear, of which there are quite a few options in Australia depending on where you live. The cities like Sydney, Melbourne, Perth, etc. obviously have more golf stores so you're likely to have a wider choice. You can get some really good basic gear that you can have fitted afterwards.
Until you have the basics it is absolutely useless trying to get fitted for clubs. Your stance, swing and swing speed, etc. are going to change so don't waste your time in getting fitted right now.
If you tell me where you live, I can recommend a few stores to you that won't rip you off.
Then I'd suggest you find a teaching professional, not just any pro - not every golf pro can teach! Some of them are pretty ****py. In 'begginer' lessons we'll teach you a proper grip, address position, alignment and the basics of the golf swing and a bit of a short game introduction (chipping, putting, etc).
Again, I'll suggest a few pros in your area to see. I know a few Down Under.
