Objective: To highlight recent reductions in mortality rates in Australia and identify conditions and population groups with the greatest potential for further reduction in mortality rates.

Design: International benchmarking and intranational comparisons of mortality rates were used to identify areas with the greatest potential for improvement.

Results: Latest data from Organisation for Economic Cooperation and Development (OECD) countries confirm that, while Japan’s death rates remain the lowest in the world, Australia’s are decreasing rapidly and we now rival Switzerland for second overall ranking. When the contributions of specific conditions are compared, the areas with the greatest potential for reductions are circulatory diseases (especially ischaemic heart disease); suicide; injury and violence; smoking-related conditions; and cancers amenable to prevention/early detection. Intranational comparisons show considerable scope for reduction in inequalities, especially those between Aboriginal and Torres Strait Islander peoples and other Australians, between males and females, and between low and high socioeconomic groups. These conditions and inequalities are highly interrelated, as differentials in health status are often mediated through broader societal inequalities.

Conclusions: Australia should aim to become the country with the lowest mortality rate in the world. This could realistically be achieved by benchmarking performance nationally and internationally, applying current knowledge and available interventions, matching policies with funding, and implementing systemic national programs and activities to promote health and prevent “illth”.

In a period when the health debate has been dominated by issues such as waiting times for elective surgery and distribution of funding responsibilities between different levels of government, a major achievement has passed without fanfare or significant media attention.

By the beginning of the 21st century, Australia had leapfrogged a group of developed countries — including Sweden, France, Italy, Iceland, Canada and Spain — to rival Switzerland for second ranking behind Japan on all-cause mortality rates (Box 1).1 Closely related to these are our rankings on total life expectancy and healthy life expectancy at birth,2 which are also among the best in the world.

Currently, Australia’s rate of reduction in death rates parallels Japan’s, and the gap in life expectancy between the two nations has also narrowed from a peak in the late 1980s.1 But our overall position is diminished somewhat by premature deaths from several potentially preventable conditions and by inequalities in their distribution. In contemporary health policy, performance in these respective areas is conceptualised as contributions to “goodness” (absolute measures of our total rates) and “fairness” (the relative distribution of health within populations).3 The interaction between the two is considerable — disadvantaged Australians die younger, principally from preventable causes. To show the impact of inequalities on our overall position, we have examined the potential gains from reducing those inequalities on the same basis as we have for the major causes of death.

While recognising the range of indicators that can be used to quantify the health and disease burden of populations, we have used mortality rates as a proxy measure because of their annual availability and general comparability across countries. It is our contention that it is now a reasonable aspiration for Australia to have the lowest mortality rate in the world within a decade, though it is unlikely that this will occur through a mere continuation of current trends.


In 1990, Armstrong4 introduced to broader population health research the notion of “Arcadian normals” — the lowest mortality rates being achieved in European and other developed countries whose people are of predominantly European background (the United States, Canada, Australia and New Zealand). He compared prevailing Australian rates with those in the best-performing country and deemed the excess to be the “proportion preventable in Australia”.

We used Organisation for Economic Co-operation and Development (OECD) health data for 2004–2006 (pertaining to the period 2000–2002) to identify Australia’s position relative to other developed countries for all-cause mortality and selected specific causes. Our analysis included Japan (the country with the world’s lowest all-cause mortality rate), Korea (which, despite high rates of death from stroke and modest overall performance, has some of the lowest rates of ischaemic heart disease and several cancers in the developed world) and several other OECD countries for which reliable recent data were available.

We indexed the difference in the age-standardised mortality rates between Australia and Japan to equal 100 points. We then calculated the number of points that could be gained by equalling the best-performing countries on a range of selected conditions. Rates in the “best-performing country” are not meant to imply finite limits. For example, while Australia’s death rate from accidental falls is the lowest in the world, current evidence suggests there is substantial scope for improvement,5 and the same probably applies in the leading country for each of the selected conditions. While these comparisons require appropriate caveats around the consistency of cause-of-death coding across OECD countries and the effect on subsequent death rates from other causes when fatal events are averted, this approach reveals many opportunities for improvement in Australia.

We also examined several known inequalities within Australia — between Indigenous and non-Indigenous people, males and females, and high and low socioeconomic groups — and expressed these using the same set of points. We ranked geographical areas and grouped them into quintiles (fifths of the population) according to the Australian Bureau of Statistics Index of Relative Socio-economic Disadvantage,6 and into deciles (tenths) according to all-cause mortality rates.


Overall, Australia is already one of the healthiest countries in the world. If each Australian all-cause mortality decile was a hypothetical sovereign nation of about two million people, the first three “nations” would already be healthier than Japan (Box 4). Our first decile would be far and away the healthiest country in the world, while our tenth would fare a little worse than the United Kingdom and the United States, but better than the countries of eastern Europe (Box 4). Collapsing our top five and bottom five deciles into two halves, the top half would still be the healthiest country in the world (Box 3), while the bottom half would be better than two-thirds of the countries in the OECD. While aggregation into deciles masks vast differences in the experiences of individuals and groups within them, these groupings serve to illustrate how well Australia performs overall and the sound base on which we can build.

Nevertheless, there is considerable room for improvement if we want to match the world’s best. Mortality is 100% higher in male blue-collar workers in Australia, and 40% higher in female blue-collar workers, than in their white-collar counterparts,8 though manual/non-manual comparisons show a lesser degree of inequality.9 The gap of 5.2 years between males and females in life expectancy recorded in 2000–2002 has narrowed even further in recent years, and Australia ranks around the middle of developed countries on this indicator. Within the sexes, a persistent 4-year gap in life expectancy between males in the least and most disadvantaged areas and a corresponding 2-year gap in females can be demonstrated.10

Age-specific comparisons with Japan show higher mortality rates for Australians at virtually every age, with the exception of men in their middle years. This is largely a legacy of very high smoking rates among Japanese males, although other lifestyle factors, including a healthier diet and low levels of overweight, appear to confer health benefits in Japan. In contrast, very low smoking rates among Japanese women, at least in the older cohorts, have been a major contributor to high life expectancy of Japanese women — almost 2 years higher than that in any other country. This advantage may decrease in the next decade as the leading edge of the smoking epidemic among younger Japanese women begins to have an impact. When these comparisons are converted to person-years of life lost, the impact of higher infant mortality and premature deaths (particularly in young Australian males) becomes apparent. In 2000, Australians lost 909 618 years of life due to death before 75 years of age. On Japan’s death rates, we could have saved 117 607 of these years of life.

What is overwhelmingly clear is that the greatest potential for improvement lies in preventing ischaemic heart disease and reducing inequalities within Australia — Indigenous/non-Indigenous, male/female, and probably socioeconomic inequalities as well. These inequalities are, to a considerable extent, expressed through potentially preventable conditions, such as heart disease, smoking-related diseases, suicide and certain types of cancer.

Although our rates of heart disease have halved in a decade, we could almost become the country with the lowest mortality rate in the world just by matching Japan or Korea on this condition alone. The Australian Government’s announcements in the 2006–07 and 2007–08 budgets in relation to improved chronic disease prevention and management are therefore particularly welcome. Although we have made steady gains in reducing cancer and now perform relatively well on injury, our suicide rates remain high and there is considerable potential for gain in the area of mental health. Unlike many previous policies, those on chronic disease and mental health have been given funding support.

Despite the progress made in Australia with reducing smoking, our analysis indicates there is further potential for reduction of smoking-related conditions. Moreover, smoking is a significant component of the three main inequalities within the Australian population. If we were to weight the analysis according to age, suicide and infant mortality would also be areas in which there would be considerable opportunity for reducing mortality rates.

There is evidence of recent modest gains in some aspects of Indigenous health,11,12 but there has been relatively little progress in reducing the overall gap between Indigenous and non-Indigenous populations in Australia.13 Although Indigenous Australians account for only about 2.5% of the population, they account for about a third of the total mortality gap between Australia and Japan. Elimination of the 17–18-year difference in life expectancy between Indigenous Australians and their non-Indigenous counterparts would add about 5 months to the total life expectancy of Australians. Massive inequalities persist — around birth, in childhood, in youth and young adulthood — culminating in a fivefold differential by middle age. Both absolute and relative disparities in life expectancy between Indigenous and non-Indigenous populations are larger in Australia than in New Zealand, Canada or the USA.14

Socioeconomic differences in mortality in Australia, particularly among men, are sizeable and have not received sufficient attention. Being male is now the single largest demographic risk factor for early mortality in developed countries,15 and it is clear that much of the widening differential between males and females in the 20th century and the recent narrowing of the sex differential is attributable to cigarette smoking.16 Inequalities between and within the sexes indicate a need for both broadly-based and sex-specific strategies.

Socioeconomic differentials in mortality between manual and non-manual workers in Australia are relatively low compared with other countries. In Australian men aged 20–59 years, the ratio of mortality in manual workers to mortality in non-manual workers was 1.34 in 1991–1995,9 whereas the lowest ratio reported in a European study of men aged 30–59 years in 1991–1995 was 1.46 in Denmark.17 The comparisons are not exact, but unlike most other measures listed in Box 3, we have not found other countries that have smaller socioeconomic differentials in mortality on this measure. Nonetheless, health inequalities in Australia are sizeable, increasing and invariably greatest for preventable conditions and in younger age groups,8 and the non-fatal consequences of these can reduce health trajectories throughout the life course.

The need now is to routinely identify the potential for gain in health in Australia through international and intranational benchmarking, and systematically assess the effectiveness and cost of interventions targeting the conditions and inequalities with the greatest potential for gain for consideration by the Council of Australian Governments. There is also a need to monitor implementation of these initiatives to ensure that the nature and scale of the interventions is optimal. In short, becoming the best requires redirection of policies and requires Australia to lift its game on measurement and the management use of national health information and to leave behind the era of resource-free policies!

These gains in health could be achieved through the application of current knowledge and systemic national effort to improve the societal factors that improve health and prevent “illth”. These measures would not only improve health — they could help contain or defer increasing health costs and enhance the sustainability of the Australian health system. It is interesting to note that Japan, the healthiest country in the world, is estimated to spend less per capita on health than Australia and has a lower annual growth rate in health expenditure, a larger proportion of health expenditure provided from public sources, a lower heart disease death rate, a much lower infant mortality rate, a lower consumption of alcohol and a lower level of obesity.1

It is reasonable for Australia to aspire to become the world’s healthiest country within a decade. But we would need to put our minds, resources and energies to the task of identifying and addressing the areas of potential gain. And above all, we would have to do much better with our hearts!
