You'll love Australia! I'm a British Nurse and made the move 10 years ago, firstly to Sydney in New South Wales and now to the Gold Coast in Queensland.
I'm not sure if you're aware of it, but the Gold coast gets a brand new tertiary hospital due to open in April 2013 and Queensland Health are about to start a recruitment drive to obtain about (sorry aboot :-) ) 200 Nurses.
If you can get an agency to help with your accreditation, sponsorship visa and recruitment I would recommend it. Try and go for an agency that won't charge a fee, to you (they charge a finders fee to the hospital). The application process can otherwise seem a bit daunting.
Even if you can't find an agency and that ascent to accreditation and sponsorship looks a little steep, go for it. Plenty of people do it on there own. First get your accreditation from AHPRA. Having it under your belt will look very good on a job application. Most hospitals in Australia are very happy to sponsor your visa. It costs them money though so may try and get you into a contract that secures a partnership with a penalty should you not stay. Not good if you end up wanting to leave and work elsewhere. They will also probably insist on you having private health cover because as your sponsors they would otherwise be responsible for all your healthcare if you became sick or injured.
On a work visa, you would of course get that freedom to work wherever your heart might take you but its worth remembering that you won't be able to work anywhere for longer than three months. Depressing if you just found your dream job and made great friends. Perhaps you should look into obtaining Permanent Residency. It's what I have. It lets you live here indefinitely and you can work wherever you like. And oh... your accelerated degree won't be a problem.
This is an amazing country and Queensland is probably the best state. The Gold Coast is a great place to live and the new University Hospital looks like it's going to be a great place to work.
Hope this is a bit of help. Good luck.
