Hi everyone, I am intending to move to Melbourne (from London) in Jan 2014 to work as an OT for a year. I am finding it really difficult to find any information/guidance about working as an OT on a working holiday visa. Does anyone know if 1) It is actually possible, and if so 2) How hard it is to find a short-term contract/locum work? I would rather not go down the Skilled Migration route if I don't have to, as it is just for a year. On the other hand, I don't want to get out there with my OT registration to find it is impossible to actually get short-term work! ​And advice at all would be greatly appreciated!
