There's a very similar thread running in Dunnunda & Godzone.
Why are you doing a 4 year degree?
You certainly don't need a degree to fly in Australia.
It can be done a lot quicker than that.
Do you know where you'll go to look for work? Are you aware of the "normal" pathways to jobs in Australia? Most folks get instructor ratings or head up north for bush flying.
Now I haven't been in Oz for over 10 years but you might want to research the current pathways to the (ultimate) job you want.
