I am currently in OZ on a working visa. It expires in a few months and I then want to go to NZ and then return back to OZ. Do I have to re apply for a visa to get back in to OZ just as a tourist and do I have to wait a while or can I return straight away??
The Australians have got it covered, if you want to enter Australia for any length of time you'll need a visa!
you can get a tourist visa for three months from most places
You should be able to apply for an ETA (Electronic Travel Authority) online at www.eta.immi.gov.au - costs AU$20, you need to be outside of Australia when you apply.
