You'll have to start with a tourist or SosBud visa, either can be sponsored by your future wife.
You'll need your passport with legal visa, a certificate from your government to prove you're free to marry, and other things such as your legalised birth certificate.
Basically, bring everything you can think of, then pack everything else because someone will ask for it sooner or later.
Add bank statements to prove you have enough money to live on without working.
You'll then apply for a KITAS (12 month) wife sponsored visa, again very likely having to prove you have funds available to live here without working (or your wife has).
