Burden of disease measures the impact of diseases and injuries on a population. It combines the years of healthy life lost due to living with ill health (non-fatal burden) with the years of life lost due to dying prematurely (fatal burden). The Australian Burden of Disease Study (ABDS) 2023 includes estimates of disease burden due to 220 diseases and injuries in Australia in 2023.
This report presents findings from the ABDS 2023, with estimates for previous years (2003, 2011, 2015, 2018) for comparison.
About the ABDS 2023
In the ABDS 2022, for the first time disease burden estimates were projected to the publication year (2022) and included estimates of disease burden due to COVID‑19. The ABDS 2023 builds on that Study by refining methods for estimating burden in the year of analysis (2023). The ABDS 2023 also makes use of more recently available data, such as the National Survey of Mental Health and Wellbeing 2020–21.
Burden from COVID‑19 was estimated using the most recent data available at the time of analysis, with assumptions made about the period without full data. Given the dynamic and ongoing nature of the COVID‑19 pandemic, these estimates may be revised in the future as more data become available for the latter part of 2023.
ABDS 2023 includes a section on the National Preventive Health Strategy 2021–30 burden of disease targets and a new data visualisation on health-adjusted life expectancy (HALE).
For more information on methods used in the Study, refer to the Technical notes.
Burden of disease analysis is a way of measuring the impact of diseases and injuries on a population (in this report, the population of Australia). It is the difference between a population’s actual health and its ideal health, where ideal health is living to old age in good health (without disease or disability).
Burden of disease is measured using the summary metric of disability-adjusted life years (DALY, also known as the total burden). One DALY is one year of healthy life lost to disease and injury. DALY caused by living in poor health (non-fatal burden) are the ‘years lived with disability’ (YLD). DALY caused by premature death (fatal burden) are the ‘years of life lost’ (YLL) and are measured against an ideal life expectancy. DALY allows the impact of premature deaths and living with health impacts from disease or injury to be compared and reported in a consistent manner.
If a disease has a high number of DALY, it is considered to have a high burden on the population. Some diseases have high fatal burden due to the number of premature deaths they cause (for example, cancers) or they cause death at younger ages, while others have high non-fatal burden due to the number of people living with the condition and/or the severity of the illness (for example, musculoskeletal conditions).
Burden estimates can be reported for diseases or injuries, which describe a specific health problem (for example, dementia). Reporting can also be for a disease group (for example, neurological conditions), which consists of a number of related diseases. There are 220 separate diseases and injuries, and 17 disease groups in the ABDS.
Living with illness or injury accounts for just over half the burden
In 2023, Australians lost 5.6 million years of healthy life (total burden, DALY) due to:
Living with illness or injury caused more disease burden than dying prematurely. Between 2003 and 2023, there has been a moderate shift from fatal burden to non-fatal burden being the biggest contributor to total burden (Figure 1.1). This is mostly driven by fewer premature deaths in recent years.

Long-term improvements in fatal burden but recent increases in non-fatal burden
Over the 20-year period from 2003 to 2023, the rate of total disease burden (the crude rate) was relatively similar (212 DALY per 1,000 population in 2003 compared with 213 DALY per 1,000 population in 2023). Underlying this was a 13% decrease in the rate of fatal burden while the rate of non-fatal burden increased by 15% over that period.
After adjusting for population ageing, there was an 11% decline in the age-standardised rate of total burden between 2003 and 2023 (Figure 1.2). This was driven by a 27% decrease in the rate of fatal burden, as the non-fatal burden rate increased by 6.3%.
Note that when compared with 2018, age-standardised rates for 2023 were higher for non-fatal, lower for fatal burden and similar for total burden. Impacts due to the COVID‑19 pandemic may have caused or affected the burden due to other causes, including impacts due to restrictions and lockdowns. Therefore, simply subtracting the disease burden due to COVID‑19 from the total burden does not necessarily reflect the true disease burden experienced had the COVID‑19 pandemic not occurred.

Chronic diseases cause most of the burden
In 2023, the 5 disease groups causing the most burden were cancer, mental health conditions & substance use disorders, musculoskeletal conditions, cardiovascular diseases and neurological conditions (Table 1.1).
Together these disease groups accounted for around two-thirds (64%) of the total burden. These disease groups include mostly chronic, or long-lasting, conditions.
Cancer | Mental health & substance use | Musculoskeletal | Cardiovascular | Neurological | |
---|---|---|---|---|---|
% of total DALY | 17 | 15 | 13 | 12 | 8 |
% of total DALY that was fatal | 91 | 2 | 3 | 74 | 49 |

Males and females experience disease burden differently
Overall and for most age groups, males experienced more total burden than females. This was driven by males having higher rates of fatal burden.
In 2023, the leading causes of total burden among males were coronary heart disease, back pain & problems and suicide & self-inflicted injuries (Figure 1.3). Among females, the leading cause was dementia, followed by anxiety disorders and back pain & problems.
Males experienced 3 times the amount of burden due to suicide & self-inflicted injuries and 2 times the amount of burden from coronary heart disease than females. Females experienced more burden than males from dementia and anxiety disorders.

Changes in leading specific causes of disease burden over time
Between 2003 and 2023, the crude rate of total burden:
- decreased for coronary heart disease, stroke, lung, bowel and breast cancer and rheumatoid arthritis.
- substantially increased for dementia, and its rank increased from the 12th leading cause of total burden in 2003 to the 2nd leading cause in 2023. However, this increase is partly due to changes in practices of coding deaths due to dementia (refer to Comparisons over time and Technical notes).
- increased for back pain & problems, anxiety disorders, chronic obstructive pulmonary disease (COPD), depressive disorders, osteoarthritis, asthma and type 2 diabetes.
Diseases that caused the most burden over the life course
Australians experience health loss from different diseases and injuries at various stages of life. Respiratory diseases caused burden throughout the life course, especially in children and the elderly. Mental health conditions & substance use disorders dominated the first half of the life course, while musculoskeletal conditions, cardiovascular diseases and cancer feature more prominently in the latter part of the life course. Neurological conditions (namely dementia) are a leading cause of burden in older Australians (aged 65 and over).

COVID‑19 burden
COVID‑19 ranked 30th among the specific diseases causing burden in 2023, accounting for 0.9% of total burden and 1.5% of all fatal burden. The burden from COVID‑19 was predominantly fatal (83%).
Australians living longer but little change in the proportion of life spent in full health
Australians are, on average, living longer and spending more years in full health (meaning no disease or injury). Years lived in full health is also referred to as the health-adjusted life expectancy (HALE).
Males and females born in 2023 could expect to live an average of 88% and 87% of their lives in full health respectively (71.6 years of the 81.3 years of average life expectancy for males and 73.6 years of the 85.1 years of average life expectancy for females).
However, years lived in ill health are also increasing, resulting in little change in the proportion of life spent in full health between 2003 and 2023.
National Preventive Health Strategy 2021–30: burden of disease targets
The National Preventive Health Strategy 2021–30 (the ‘Strategy’) outlines the long-term approach to prevention in Australia. The Strategy aims to address the wider determinants of health, promote health equity and decrease the overall burden of disease through a whole-of-systems approach to prevention (Department of Health 2021).
There are 6 burden of disease specific targets in the Strategy and data from the ABDS 2023 can be used to monitor 3 of the 6 targets.
Table 1.2 shows how the burden of disease measures in 2023 compare with the baseline measures (the year 2018) for each reportable target. Between 2018 and 2023, there has been little change in the proportion of the first 25 years and 0–4 years lived in full health (ranging between 91 and 92%). There has also been little change in the average number of years lived in full health (approximately 72 years for males and 74 years for females).
Aim | Target | Sex | 2018 (baseline) | 2023 estimate | Comparison to 2018 |
---|---|---|---|---|---|
All Australians have the best start in life | The proportion of the first 25 years lived in full health will increase by at least 2 percentage points by 2030 | Persons | 92.1% of first 25 years were lived in full health | 91.6% of first 25 years were lived in full health | –0.5(a) |
All Australians have the best start in life | The proportion of the first 0–4 years of life lived in full health will increase by at least 3.5 percentage points by 2030 | Persons | 92.0% of first 5 years were lived in full health | 91.4% of first 5 years were lived in full health | –0.6(a) |
All Australians live in good health and wellbeing for as long as possible | Australians have at least an additional 2 years of life lived in full health by 2030 | Males
Females | 71.5 years lived in full health
74.0 years lived in full health | 71.6 years lived in full health
73.6 years lived in full health | 0.1 years
-0.4 years |
(a) This is the difference in the proportion of the first 25 or 5 years lived in full health between 2023 and the baseline (2018).

Estimates for 2023 are projections so progress against the targets may change as 2023 data becomes available. COVID‑19’s impacts on burden and the health of the Australian population may affect progress against these targets.
