With that amount of jet time, you would have to be a shoe-in with Jetstar, Ozjet, Alliance or the the new Qantas Freight operation. Slightly further out is Air Pacific always looking for experienced drivers. India, Japan etc - c'mon the papers have been full of ads for 737 jocks. You live in Australia, so you already know that.
Or have you set some limitations, like only want to live in Sydney and fly 3 days a week, never on weekends, no overnights?
