Quick questions on Comparing Australia's health status with other OECD countries: HSC Health and Movement Science Focus Area 1

Australia is one of the OECD's strongest performers - around 83 years total (2023 OECD figures; AIHW reports roughly 81 for males and 85 for females). Only a small group of countries rank clearly above Australia: Japan, Switzerland, Spain, Italy and South Korea among them. This is a genuine top-tier result.

Australia has low infant mortality (about 3 per 1000 live births, 2022) and falling avoidable (preventable) mortality, especially from cardiovascular disease, where age-standardised death rates have fallen markedly over decades. Australia is below the OECD average for premature mortality on most measures, though the Nordic countries, Japan and Estonia report even lower infant mortality (around 2 per 1000).

This is Australia's clear weakness. Approximately two-thirds of Australian adults are overweight or obese (about 66 percent; AIHW/ABS), with around 1 in 3 adults (about 31 percent) in the obese range. Australia ranks among the higher-obesity OECD countries, well above Japan and South Korea (adult obesity under about 7 percent) and worse than most of Western Europe.

Australia spends approximately 10 percent of GDP on health (2022 to 2023), close to the OECD average. The United States is a dramatic outlier at roughly 16 to 17 percent of GDP (2022) - far more than any other OECD country - yet has worse outcomes. This contrast is the single most exam-useful fact in the topic.

The countries above Australia on life expectancy (Japan, South Korea, much of Western Europe and the Mediterranean) tend to have lower obesity and, in some, lower smoking. Lower population risk factors mean less Type 2 diabetes, cardiovascular disease and cancer, which lifts longevity. Australia's high overweight and obesity is the single biggest behavioural drag on its ranking.

Countries with universal, accessible primary care and low cost barriers (Japan, the Nordics, most of Western Europe, and Australia via Medicare) catch chronic disease earlier and treat it. The United States is the cautionary case: it spends by far the most (about 17 percent of GDP) but its fragmented private-insurance model leaves many uninsured or underinsured, so access is unequal and avoidable mortality is higher. Spending does not buy outcomes; equitable access does.

A national average can hide large internal gaps. Australia's average is pulled down by the roughly 8-year life-expectancy gap for Aboriginal and Torres Strait Islander peoples - an inequity that the top OECD performers, with smaller internal gaps, do not carry to the same degree.

STIMULUS. Japan spends about 11 percent of GDP on health with a life expectancy of about 84 years; the United States spends about 17 percent with a life expectancy of about 77 years. Using the data, explain what this shows about the link between health spending and outcomes.

Analyse Australia's health status relative to other OECD countries, and assess the extent to which the comparison reveals both strengths and weaknesses. [8 marks]
