Australia’s life expectancy is the third highest in the world for males and the seventh highest for females. Life expectancy in Australia in 2010 was 79.5 years for males and 84.0 years for females. Australia has the highest rates of skin cancer in the world, while cigarette smoking is the largest preventable cause of death and disease, responsible for 7.8% of the total mortality and disease. Ranked second in preventable causes is hypertension at 7.6%, with obesity third at 7.5%. Australia ranks 35th in the world and near the top of developed nations for its proportion of obese adults and nearly two thirds (63%) of its adult population is either overweight or obese.
Total expenditure on health (including private sector spending) is around 9.8% of GDP. Australia introduced universal health care in 1975. Known as Medicare, it is now nominally funded by an income tax surcharge known as the Medicare levy, currently set at 2%. The states manage hospitals and attached outpatient services, while the Commonwealth funds the Pharmaceutical Benefits Scheme (subsidising the costs of medicines) and general practice.
