Karmen's Going to Australia

Oh my goodness, it looks like a visit to Oz needs a visa or an ETA:

If you are planning a holiday visit or a short business trip to Australia, you will need to apply for either a visa or an ETA (Electronic Travel Authority). An ETA will let you spend up to three months in Australia.

Important: You may not be permitted to enter Australia unless you are in good health and have no criminal convictions.
