I need help with my career and getting to australia!

hi guys, this is my first thread so hope it gets some replies! im in need of some help basically, im 30 years old and having travelled the last 3 years and wanting to live in australia have decided its time for a change of career. Im a bit worried about the competition of a mature student getting onto a physio degree course next year so have applied for a teaching course, although i would prefer physio as ha career. i have to bear in mind though at the end of it i will want to be getting over to Australia to live eventually so i was just wondering if anyone had any advice? My plan is to get my degree and then look at moving to oz, but i know in the tests and requirements you need a couple of years experience in a practise.Has anyone done this and can anyone give me some info if so? im worried ill finish my degree, not be able to find work as ive heard physio is really tough to get a job in once qualified and wont be able to gain experience to get residency in australia. If anyone can help id REALLy appreciate it! many thanks
