๐ Key Information Summary
- Aboriginal and Torres Strait Islander peoples experience a life expectancy gap of approximately 8 years for males and 8 years for females compared with non-Indigenous Australians (AIHW, 2023).
- Chronic diseases โ cardiovascular disease, type 2 diabetes, chronic kidney disease, respiratory disease and cancer โ account for the majority of the health gap and are largely preventable.
- Type 2 diabetes prevalence in Aboriginal and Torres Strait Islander adults is 3โ4 times that of the non-Indigenous population; early screening from age 18 is recommended.
- Rheumatic heart disease (RHD) remains endemic in many remote and regional communities, with incidence rates among the highest in the world.
- Culturally safe, trauma-informed care is a clinical obligation โ not merely an aspiration โ and requires ongoing self-reflection, cultural humility and partnership with Aboriginal Community Controlled Health Organisations (ACCHOs).
- The Australian Government's National Agreement on Closing the Gap (2020) sets 17 socioeconomic targets with shared decision-making between governments and Aboriginal and Torres Strait Islander representatives.
- Medicare Benefits Schedule (MBS) items 715 (health assessment) and 721/723 (GP Management Plans / Team Care Arrangements) are central to chronic disease management in primary care for Indigenous patients.
- Social determinants โ housing, education, incarceration, food security and racism โ are the primary drivers of health inequity and must be addressed alongside clinical care.
- Smoking rates remain approximately 2.5 times higher in Indigenous Australians; culturally tailored cessation programmes show better engagement than generic approaches.
- GPs should proactively offer Aboriginal and Torres Strait Islander health checks (MBS 715) to every Indigenous patient and link findings to GP Management Plans.
- Remote and very remote communities face acute workforce shortages; telehealth and visiting specialist models are essential to close access gaps.
- Strengthening the Indigenous health workforce โ including Aboriginal Health Workers and Aboriginal Health Practitioners โ is a key Closing the Gap priority.
Introduction & Australian Epidemiology
Aboriginal and Torres Strait Islander peoples are the First Nations peoples of Australia, with continuous connection to Country spanning more than 65,000 years. Health and wellbeing are understood holistically, encompassing physical, social, emotional, cultural and spiritual dimensions โ a perspective recognised in the National Aboriginal Health Strategy and increasingly embedded in Australian health policy.
Despite improvements over recent decades, significant health inequities persist between Indigenous and non-Indigenous Australians. These disparities are not explained by biology alone; they are driven by the legacy of colonisation, dispossession, intergenerational trauma and ongoing systemic racism. The burden of chronic disease, mental health conditions, communicable diseases and perinatal complications is disproportionately borne by Aboriginal and Torres Strait Islander communities.
As of the 2021 Census, approximately 984,000 people in Australia identify as Aboriginal and Torres Strait Islander, representing 3.8% of the total population. Around 38% live in major cities, 22% in inner regional areas, 20% in outer regional areas, 10% in remote areas and 9% in very remote areas. Health outcomes vary markedly by remoteness, with substantially worse indicators in remote and very remote settings.
General practitioners are frequently the first point of contact with the health system for Aboriginal and Torres Strait Islander people and play a pivotal role in preventive care, chronic disease management, culturally safe practice and advocacy. This article summarises key health inequalities, the chronic disease burden, principles of culturally safe care and the national Closing the Gap framework as they relate to Australian primary care.
Health Inequalities & Key Health Statistics
The health gap between Aboriginal and Torres Strait Islander peoples and other Australians is wide, persistent and structurally determined. Understanding the scale and nature of these inequalities is essential for every clinician working in Australian primary care.
Life Expectancy & Mortality
- Life expectancy at birth: Indigenous males 71.6 years vs non-Indigenous males 80.2 years; Indigenous females 75.6 years vs non-Indigenous females 83.4 years (2015โ2017 ABS estimates).
- Age-standardised mortality rate is approximately 1.5 times higher for Indigenous Australians.
- Infant mortality: Indigenous rate approximately twice the non-Indigenous rate (4.6 vs 3.1 per 1,000 live births, 2019).
- The leading causes of death are ischaemic heart disease, diabetes, chronic lower respiratory diseases, cerebrovascular disease and lung cancer.
Key Comparative Statistics
| Indicator | Indigenous | Non-Indigenous | Ratio / Gap |
|---|---|---|---|
| Life expectancy (male) | 71.6 years | 80.2 years | 8.6-year gap |
| Life expectancy (female) | 75.6 years | 83.4 years | 7.8-year gap |
| Type 2 diabetes prevalence | ~12% | ~4% | 3ร higher |
| Current smoking (adults โฅ18) | ~40% | ~14% | ~2.9ร higher |
| End-stage kidney disease (incidence) | Higher | Baseline | ~2โ3ร higher |
| Rheumatic heart disease notification | ~60 per 100,000 (NT) | Rare | Near-unique burden |
| Hospitalisation for all causes | Elevated | Baseline | 1.4ร higher age-standardised |
Social Determinants Driving Inequity
Health inequalities cannot be addressed through clinical care alone. The major upstream determinants include:
- Housing and infrastructure: Overcrowding rates 3โ4 times higher; limited access to safe water and sanitation in some remote communities.
- Education: Lower Year 12 attainment; limited access to culturally appropriate health literacy resources.
- Employment and income: Higher unemployment, lower median household income, greater reliance on government payments.
- Incarceration: Aboriginal and Torres Strait Islander peoples constitute ~30% of the adult prison population but only 3.8% of the general population. Health care in custody is often inadequate.
- Food security: Remote stores often charge 50โ100% more for fresh fruit and vegetables compared with urban supermarkets.
- Racism and discrimination: Documented as an independent risk factor for poor mental and physical health outcomes.
Chronic Disease Burden
Chronic diseases are the primary driver of the Indigenous health gap, accounting for approximately 70% of the life expectancy difference. The five major contributors are cardiovascular disease, type 2 diabetes, chronic kidney disease, chronic respiratory disease and cancer. Many of these conditions share common risk factors โ smoking, obesity, physical inactivity and poor nutrition โ and are amenable to prevention and early intervention in primary care.
Cardiovascular Disease
- Ischaemic heart disease is the leading single cause of death in Aboriginal and Torres Strait Islander peoples.
- Acute rheumatic fever (ARF) and rheumatic heart disease (RHD) remain endemic, particularly in NT, northern WA and northern QLD, predominantly affecting children and young adults.
- Absolute cardiovascular risk (CVR) assessment using the Australian CV Risk Calculator should be offered from age 30 (or earlier with risk factors). Indigenous Australians should be flagged as having higher baseline risk.
- Statin therapy for primary prevention is recommended at lower thresholds (โฅ10% 5-year absolute CVR vs โฅ15% in general population guidelines for some risk categories).
Type 2 Diabetes
- Prevalence approximately 3โ4 times the non-Indigenous rate; onset is often a decade earlier with more aggressive complications.
- Screening should commence from age 18 (or earlier if overweight/obese with additional risk factors) using fasting glucose, HbA1c or oral glucose tolerance test.
- Diabetic kidney disease, retinopathy and peripheral neuropathy develop earlier and more frequently.
- Multidisciplinary care with access to diabetes educators (preferably Indigenous), dietitians and podiatrists is essential.
Chronic Kidney Disease (CKD)
- Indigenous Australians are 2โ3 times more likely to have CKD and disproportionately progress to end-stage kidney disease (ESKD).
- ESKD incidence rates in remote NT communities are among the highest in Australia.
- Regular eGFR and urine ACR monitoring should begin from age 18 in all Indigenous patients.
- ACE inhibitors / ARBs are first-line renoprotective therapy; SGLT2 inhibitors (e.g., dapagliflozin, empagliflozin) are now recommended for CKD with or without diabetes.
Chronic Respiratory Disease
- Chronic obstructive pulmonary disease (COPD) and asthma prevalence is higher, linked to smoking, indoor biomass smoke exposure and childhood respiratory infections.
- Bronchiectasis remains significantly more common in Indigenous children, especially in remote communities.
- Smoking cessation is the single most impactful intervention for respiratory health.
Cancer
- Cancer mortality is approximately 1.4 times higher in Indigenous Australians, with lower five-year survival rates attributed to later stage at diagnosis, lower screening participation and reduced access to treatment.
- Lung, liver, cervical and head/neck cancers are disproportionately represented.
- Cervical cancer is largely preventable through HPV vaccination and regular screening; the National Cervical Screening Program remains a priority area.
Key Medications for Chronic Disease Management
Culturally Safe Care
Cultural safety extends beyond cultural awareness or cultural sensitivity. It requires that the patient determines whether care is safe and respectful โ placing the locus of assessment with the recipient of care, not the provider. In Australian general practice, culturally safe care for Aboriginal and Torres Strait Islander patients is both an ethical obligation and a clinical necessity: patients who feel unsafe or judged are less likely to attend appointments, disclose symptoms, adhere to treatment or return for follow-up.
Core Principles of Culturally Safe Practice
Trauma-Informed Care
Many Aboriginal and Torres Strait Islander patients carry the cumulative burden of intergenerational trauma (forced removals, Stolen Generations, institutional racism) and individual trauma. A trauma-informed approach involves:
- Recognising the high prevalence of trauma without requiring patients to recount it.
- Ensuring physical and emotional safety in the clinical environment.
- Offering choice and control at every step โ including the option to stop, defer or bring a support person.
- Avoiding re-traumatisation through insensitive questioning, physical examination without explanation, or involuntary treatment.
Practical Steps for General Practice
| Action | Detail |
|---|---|
| Identify Indigenous patients | Proactively and respectfully ask all patients about Aboriginal or Torres Strait Islander identification at registration. This enables access to MBS 715 and other targeted programmes. |
| Employ Aboriginal Health Workers / Practitioners | AHWs and AHPs bridge clinical and cultural worlds. They improve engagement, health literacy and follow-up. Fund positions through practice incentive payments and state/territory programmes. |
| Display culturally safe signage | Welcome signage in local language(s), Aboriginal and Torres Strait Islander flags, acknowledgement of Country in waiting areas. |
| Flexible appointment systems | Allow longer consults, walk-in availability and reduced emphasis on strict punctuality for non-acute visits. Avoid punitive policies for missed appointments. |
| Link with ACCHOs | Establish referral pathways and shared care arrangements with local Aboriginal Community Controlled Health Organisations. |
| Use of interpreters | For patients whose first language is not English (including many remote community residents), arrange an interpreter โ ideally from the Aboriginal Interpreter Service (NT) or equivalent state service. Avoid using family members (especially children) as interpreters for sensitive topics. |
Closing the Gap Priorities
The National Agreement on Closing the Gap (July 2020) represents a landmark shift in Australian health policy. Developed through genuine partnership between the Coalition of Aboriginal and Torres Strait Islander Peak Organisations (Coalition of Peaks) and Australian governments, the agreement establishes 17 socio-economic targets across four Priority Reforms and 17 outcome areas.
Four Priority Reforms
Key Health-Related Outcome Areas
- Outcome Area 1 โ Life expectancy: Close the life expectancy gap by 2031 (progress: limited).
- Outcome Area 2 โ Babies with healthy birthweight: Increase the proportion of Aboriginal and Torres Strait Islander babies with a healthy birthweight to 91% by 2031.
- Outcome Area 3 โ Early childhood development: Increase proportion of children assessed as developmentally on track in all five AEDC domains.
- Outcome Area 4 โ Children in out-of-home care: Reduce the rate of over-representation.
- Outcome Area 14 โ Social and emotional wellbeing: Reduce suicide rates towards zero (an aspirational, not numerical, target).
Role of General Practice in Closing the Gap
- Provision of annual Aboriginal and Torres Strait Islander health assessments (MBS Item 715).
- Development and review of GP Management Plans (MBS 721) and Team Care Arrangements (MBS 723) for patients with chronic conditions.
- Practising within the Practice Incentives Program (PIP) Indigenous Health Incentive framework โ registering Indigenous patients, completing health assessments and linking to chronic disease management.
- Supporting continuity of care โ preferential booking with the same GP, recall systems and outreach into community settings.
- Advocacy: GPs are trusted community voices. Writing letters of support for housing, NDIS access or social services can be as clinically important as prescribing medication.
ACCHOs: The Preferred Model
Aboriginal Community Controlled Health Organisations (ACCHOs) are the largest single provider of primary health care to Aboriginal and Torres Strait Islander peoples in Australia, delivering over 3 million episodes of care annually through more than 200 organisations. ACCHOs are governed by local Aboriginal and Torres Strait Islander communities and deliver holistic, comprehensive, culturally safe care. GPs in mainstream practice should establish strong referral and shared-care relationships with their local ACCHO.
Special Populations
Within the Aboriginal and Torres Strait Islander population, certain subgroups face additional layers of vulnerability. Tailored approaches are required.
Children & Young People
Pregnant Women
Elderly / Elders
Remote & Very Remote Communities
