Hi Rosie
I am an OT and have just began the whole process, a workmate of mine who is further along the process than me is also a forum member "crazylady", we are both applying to queensland health (crazy has just been offered a position) we have both found out it is a whole lot easier to get offered a job first and then apply for a visa.
We are both going for permenant resident visas, they take longer than temp ones but give you better opportunties and rights whilst in OZ. OTs are in hot demand in oz, have you checked ot journal and ot news? they have been advertsing there for months also surf the net especially on particular states health sites as they often have a work for us section etc (E.G QUEENSLAND HEALTH).
Ask us anything and i hope we can all help each other (you never know we could all be working together one day lol).
DARREN
