  Health spending in 2023–24

  In 2023–24, Australia spent an estimated $270.5 billion on health goods and services– an average of approximately $10,037 per person. In real terms (adjusted for inflation), health spending increased by 1.1%, or $2.8 billion more than spending from 2022–23. 

  In 2023–24, health spending accounted for 10.1% of the gross domestic product (GDP) in Australia, approximately 0.2 percentage points higher than in 2022–23.

From the bottom:

  In Australia, 15% of all expenditure on health care comes directly from individuals in the form of out‐of‐pocket fees — this is almost double the amount contributed by private health insurers.

  There is concern that vulnerable groups — socio‐economically disadvantaged people and older Australians in particular, who also have higher health care needs — are spending larger proportions of their incomes on out‐of‐pocket fees for health care. 

  A 2019 study identified that one in three low income households are spending more than 10% of their income on health care. 

There's little to no public advertising of prescription drugs, cheap generics are widely available from federal scale bulk negotiation deals.

Health outcomes are greater life expectancy than the US, national scale cancer survuival rates are better by a few percentage points (IIRC - they are close but higher).

Australia has long had an innate "we're all in this together" society built on individualism. It's not great, it's not perfect, but the first instinct is generally to look after our own - across the board.

When I was in the USA just paying for things like a GP and a single specialist didn't seem outrageous coming from Australia.

If I worked in the US, I would have health insurance and would be paying lower out of pocket costs than I would in Australia. Combined with the higher salary and cheaper housing that's a pretty good deal.

Edit:

We allegedly have universal healthcare but that doesn't cover any actually competent specialist (need private healthcare for this) so paying $400 for 25 minutes of a psychiatrist every 2 months and $95 for 7 minutes of a GP is common.
