In the US, with insurance, they're typically like $300.
I live in Western Australia and it's all done by St John's Ambulance. My partner has needed two non-urgent ambulance call-outs (transfer to a public hospital), which were both charged at ~$500. She's on my private 'extras'* insurance policy, and my insurer fully covers an unlimited amount of ambulance transfers ($50 co-pay for non-urgent). I believe this to be a common thing for this type of insurance policy - I'm not on any fancy tier of coverage.
HOWEVER:
A couple of years ago my significant other had an accident in a public area where she unable to move or call an ambulance. A nearby resident heard her yelling and called the police / ambulance. The paramedics seemingly had the authority to take her away from the police officers who were questioning her. She was taken to the nearest public hospital and was discharged from the ED shortly thereafter. She never received a bill. She's only young and the accident (very apparently) occurred as a result of drug use, so I think that the paramedics operating the ambulance are allowed discretion when deciding whether or not somebody should be charged.
* Physio, psychology, dental.etc. (all non-emergency). These services are not (fully) covered by our public health system, so many people opt for private cover. These policies work heavily on annual limits, so it's a bit unfair to call them insurance.
I've had to take an ambulance to hospital a number of times. Cost to me: eu0.
I've also had to stay in hospital a couple of times, had a couple operations. Cost to me: eu0.
Of course, I pay regularly into the Austrian health system with portions of my pay check every month. But there is no suffering beyond that, if I have to have any medical procedures or take the ambulance for an accident.
After being discharged I gave them my passport and the hospital bill was $0 while the ambulance bill was around $950 Aud.
When I moved to singapore to live I got appendicitis. I called a taxi and paid $9 to go to the hospital. Too scared to get ambulance now even if it’s covered by insurance.
There is a big private health care industry in Australia (for better or worse) that's not employer based (you see adverts on TV), so I'm guessing a lot of Kiwis just get private care in the AU.
But I'm wondering how much it costs an actual Australian resident/citizen with medicare. I know as a non-resident, a doctor cost around $70 ~ $80 (went once in Melbourne and once in Sydney) and I saw a real doctor. That's a far cry from America where you pay $200+ to see a Nurse Practitioner (yes, pretty advanced, but still not an MD).
