Migration In?

So, one a worksheet that I'm working on for a missionboard that I feel highly favorable about, the question arose: "Ideas on how to enter the field?" And I found myself in a dilemma...I don't know!

Australia is a very hard field to enter, I've been told, because they don't just let anybody move in...which makes sense. SO, the question becomes how do I enter Australia? With a "business" backing me (such as a church)? As a teacher or some such thing for four years that I might obtain citizenship before embarking on the "main ministry"? Or what? Ah, pondering...so many things to think about!!!
