W.Australia has a land area three time that of Texas with the bulk of the 2.9 million in population clustered about the capital city Perth.
In the rest of the state there are volunteer Ambulance services subsidised by state and federal government and a fleet of Royal Flying Doctor air ambulances.
RFD(WA) comes in at ~ $80 million AUD / annum in state support (for better or worse - https://www.abc.net.au/news/2024-07-24/rural-gp-slams-royal-... )
They assert to have a "value" to the state of $4.1 billion AUD over 30 years - https://www.flyingdoctor.org.au/wa/
Every day, the Royal Flying Doctor Service in Western Australia retrieves 29 people.
Australia is also going bankrupt just slightly faster than the United States. Looks like deficit spending and debt levels are only trending the wrong direction there as well.
I am all for flight for life as we call it here, but that is different than saying we should have a network of ambulances across massive swabs of mostly empty terrain.
I am willing to hazard that the Australian airlift response is slower than your average ambulance response in Sydney.
