I don't know about Australian health care, but find ours , where I am just excellent.
I have also used private, for profit Healthcare in the US and Canada. All are equivalent, imo.
Canada's system is costly to operate but some where I had read there is more money put into the US system per capita and many fall through the cracks.
The only way " Healthcare " will improve is if the user takes personal responsibility for there own.
Increasingly, we are more fat, less fit and more miserable.... and less faithful to Our Maker.
There must be a connection. God Bless you all.
