Yes I do realise that my chances are better with overseas airlines, Asia, Pacific Island, or even Africa etc....
The USA are also accepting Australians on the E3 visa. There are quite a number over there right now flying ERJ 175s and CRJs for the regional airlines building jet time. A few late starters as well, much older than 29. Get the minimums and head over to the US. Once you have jet time, more doors open for you when you want to move on from the US regional scene.
