In Oz...
...or at least in Queensland, the bill for a non-Queensland resident is around AU$1000.
If you need an ambulance here whilst on vacation, just give a Queensland address (make it up) and tell them you have lived there for more than three months = no bill.

In New South Wales (Australia)
The bill for an ambulance is approx $80/km.

Ambulance insurance is about $20/annum and means you ride for free. If you don't have it, you pay.
