I don't know your hours or experience.
I went up north to Kununurra and got a job up there. Not that easy. I started off on singles and after I had about 1000 hours TT I moved onto the twins.
Some get onto twins by instructing.
Bank runners etc usually want a fair bit of experience. Most companies that do twin work only want about 500-1000 hours on twins first.
So, if you have less than 1000 hours TT you will have to move to places like Kununurra, Mt Isa, Torres Strait islands and so on.
