A lot of my family have moved out there, dad's side have been there since hmm way before I was born, they love it out there.
My cousin on mum's side moved over a year ago with her boyfriend (fiancé now) she does love it there but she has found it hard because she misses her family, she was only supposed to be there a year but found out she is staying there now so she obviously loves it a lot
The only thing I would say is check on money as my auntie said it is actually more expensive out there, cousin is ok because her fiancé's company is paying for there flat & they are both working. They are in Sydney so maybe its just there that is more not sure though, my best friend is out there at the moment though travelling she is having trouble finding a job & told me things are expensive too.
You could always go out for a year on a work visa and see how you like it
At least there is sun down under unlike here lol
