Hi Jane,
I'm a bit out of the "mainstream" as I work in child and adolescent MH.
However, I did a bit of everything when I first arrived. I would say you would have no probs on the job front. They do things a little differently here, and in all the services I've worked here, (adult, psychogeriatric, d+a, and kids) they all seem to be a little bit behind in some areas.
I would recommend agency work when you get here
1) cos you can work when and where you like
2) it gives you ideas about where you might want to end up as a permanent staff member
I'm not sure what you mean about being signed up for 12 months.....You do as much, or as little as you want.....for as long as you want.
I used what used to be called NASA, who are now called Nursing agency of australia...go here,
http://www.nursingagency.com.au/index.html . They were pretty good, just gave you the hours you wanted, didn't ring you at horrid times when you hadn't put your name down as available to work!
The other option is to join a hospital casual pool - that way you will probably be eligible to apply for govt jobs when they come up.
Have a peek at
http://www.flinders.sa.gov.au/, That's the hospital I work at.
