Hi Rupert and All
I done a little bit of research and I agree that best visa is 189 (skilled independent visa) but processing will take 2-3-4years. (According to emigration officer I meet in Dublin job show 2 years ago)
190 visa is not covering Melbourne area.
To open working holiday visa is impossible because my age is 38.
So, I don’t see anything possible at the moment in short/quick terms.
I was in Melbourne 2 times already and it’s a lovely city it and I would be very happy to be working over there.
