Clairemolly, I think it's disgraceful how you've been treated, I would be sending in a formal letter of complaint! I think when you received any conformation that they (AHPRA)had received your application 9months ago then your application should be based on the rules then.
Ive been here 5 years and with a DipHE, so I'm glad I got in, but to only accept Degree level nurses then Australia is making a mistake. Yes there are Graduate nurses without jobs but that's because employers want experienced nurses. I remember qualifying in the UK 10 years ago and we all struggled to get jobs too. I'm in WA and there is a job freeze here at the minute because of Fiona Stanley opening next year.
They are apparently needing thousands of extra nurses to fully staff the new hospital, which I'm led to believe is coming from (partly) a recruitment drive from the UK. AHPRA is a pawn in a government led change of policy.
