Aboriginal and Torres Strait Islander people

Key findings

  • There has been significant declines in the proportion of Aboriginal and Torres Strait Islander people smoking and consume alcohol that exceeds lifetime risk guidelines (consuming more than two standard drinks per day on average).
  • The prevalence of smoking by Indigenous people has declined from 55% in 1994 to 45% in 2014–15.
  • The proportion of Indigenous people that consume alcohol as levels that exceed lifetime risk guidelines has reduced from 19% in 2008 to 15% in 2014–15.
  • In 2011, tobacco use accounted for 12% of the burden of disease for Indigenous Australians. This accounts for 23.3% of the health gap between Indigenous and non-Indigenous Australians.
  • In 2016, more than 1 in 4 (27%) Indigenous Australians used an illicit drug in the last 12 months. This was 1.8 times higher than for non-Indigenous Australians (15.3%).
  • The most commonly used illicit drug by Indigenous Australians is cannabis (16.7%), followed by the non-medical use of pharmaceutical drugs (11.0%).
  • Of clients of alcohol and other drug, treatment services, 15% were Indigenous Australians aged 10 and over, which is an overrepresentation relative to their population size. 

Currently there are almost 800,000 Aboriginal or Torres Strait Islander people (see Box ATSI1) living in Australia, accounting for 2.8% of the Australian population [1]. There are substantial differences in measures of health and welfare between Aboriginal or Torres Strait Islander people and non-Indigenous Australians.

Box ATSI1: Aboriginal and Torres Strait Islander people

The terms ‘Aboriginal and Torres Strait Islander people’ is preferred in Australian Institute of Health and Welfare (AIHW) publications when referring to the separate Indigenous peoples of Australia. However, the term ‘Indigenous’ Australians is used interchangeably with ‘Aboriginal and Torres Strait Islander’ in order to assist readability.

The Australian Burden of Disease Study identified that Aboriginal or Torres Strait Islander people experience a burden of disease that is 2.3 times the rate of non-Indigenous Australians [2]. The gap in the disease burden is due to a range of factors including disconnection to culture, traditions and country, social exclusion, discrimination and isolation, trauma, poverty, and lack of adequate access to services [3]. Tobacco, alcohol, and other drugs are key risk factors contributing to the health gap between Indigenous and non-Indigenous Australians [2].

Box ATSI2. Data sources examining tobacco, alcohol and other drug use by Aboriginal and Torres Strait Islander people

There are a number of data sources that provide information about tobacco, alcohol and other drug use by Aboriginal and Torres Strait Islander people.

The National Aboriginal and Torres Strait Islander Social Survey (NATSISS) [4] and the Australian Aboriginal and Torres Strait Islander Health Survey (AATSIHS) [5] collected by the ABS are designed to obtain a representative sample of Indigenous Australians. In relation specifically to tobacco smoking, the ABS has consolidated data from six large, national, multistage random household surveys to identify trends between 1994 and 2014–15 [6].

The AIHW’s National Drug Strategy Household Survey (NDSHS) uses a self-completion questionnaire to capture information about drug and alcohol use among the general Australian population; however it is not specifically designed to obtain reliable national estimates for Indigenous people. In 2016, 2.4% of the NDSHS (unweighted) sample aged 12 and over (or 568 respondents) identified as being of Aboriginal or Torres Strait Islander origin. The estimates produced by the NDSHS should be interpreted with caution due to the low sample size [7].

There are also other data sources that provide information relevant to Aboriginal and Torres Strait Islander people.

  • Australia’s Burden of Disease study analyses the impact of nearly 200 diseases and injuries in terms of living with illness (non-fatal burden) and premature death (fatal burden). In 2015, a report was released that provides estimates of burden of disease for Indigenous and non-Indigenous Australians [8].

  • The Alcohol and Other Drug Treatment Services National Minimum Dataset (AODTS-NMDS) contains information on treatment provided to clients by publicly funded alcohol and other drug services including Indigenous clients [9].

  • The Online Services Report (OSR) contains information on the majority of Australian Government-funded Aboriginal and Torres Strait Islander substance use services [10].

  • The National Perinatal Data Collection covers each birth in Australia and includes information on Indigenous mothers and their babies [11].

Tobacco smoking

While tobacco smoking is declining in Australia, it remains disproportionately high among Indigenous Australians. Data from the Australian Bureau of Statistics (ABS) has shown: 

  • In 1994, the Indigenous Australian survey data showed that 55% of Indigenous Australians aged 18 and over were smokers; 20 years later, in 2014–15, this had declined to 45% (Table S3.4).
  • Over a similar 20-year period, the proportion of non-Indigenous smokers aged 18 and over declined, from 24% in 1995 to 16% in 2014–15 (Table S3.5).
  • There appears to have been no change to the gap in smoking prevalence between the Indigenous Australian adult population and the non-Indigenous Australian adult population from 1994 to 2014–15. Even though the Indigenous Australian smoking rates are declining, the non-Indigenous rate is declining at a similar rate, therefore the gap remained constant [6] (Figure ATSI1).

Most of the decline in smoking occurred in non-remote areas. Over the 20-year period, the proportion of Indigenous Australians aged 18 and over in non-remote areas who were smokers declined from 55% to 42%, while the proportion in remote areas remained relatively stable at between 54% and 56% (Table S3.4).

In 2014–15, Indigenous males were more likely than Indigenous females to be smokers (47% compared with 42%) [1].

Geographic trends

The 2014–15 NATSISS provides estimates of tobacco smoking for Indigenous Australians by jurisdiction. According to the 2014–15 NATSISS, 39% of Indigenous Australians aged 15 and over smoked daily. Those from the Northern Territory (45%) and Western Australia (42%) surpassed this national average, while Indigenous Australians from South Australia (35%) were the least likely to be a current daily smoker [4] (Table S3.3).

Tobacco smoking in pregnancy

Indigenous Australians are at an elevated risk of smoking during pregnancy compared with non-Indigenous Australians. The National Perinatal Data Collection showed that, in 2016:

  • The rate of Indigenous mothers smoking at any time during pregnancy decreased from 50% in 2009 to 43% in 2016 (age standardised).
  • Almost 1 in 2 (42.8%) Indigenous mothers reported smoking at some time during pregnancy – compared with 11.6% of non-Indigenous mothers (age-standardised).
  • The rate of Indigenous mothers quitting smoking during pregnancy was 26% compared with 13% of non-Indigenous mothers (based on mothers who reported smoking in the first 20 weeks of pregnancy and not smoking after 20 weeks of pregnancy; age standardised) [11].

Alcohol consumption

Abstinence (non-drinkers)

  • The 2016 NDSHS found that Indigenous Australians aged 14 and over were more likely to abstain from drinking alcohol than non-Indigenous Australians (31% compared with 23%, respectively) and abstinence among Indigenous Australians has been increasing since 2010 when it was 25% [7] (Table S3.1).
  • This pattern is consistent with data from the 2012–13 AATSIHS, where 28% of Indigenous Australians reported abstaining from drinking compared with 18% of non-Indigenous Australians [5].

Lifetime risk

  • The 2014–15 NATSISS found that the proportion of Indigenous Australians aged 15 years and over who exceeded the NHMRC lifetime risk guidelines for alcohol consumption (consuming more than 2 standard drinks per day on average) decreased between 2008 and 2014–15 (19% compared with 15%; non age-standardised proportions). The overall change is largely due to a decline in non-remote areas (19% in 2008 to 14% in 2014–15) [4] (Table S3.6).
  • Comparisons between Indigenous and non-Indigenous Australians are only available using age-standardised data from the 2012–13 AATSIHS and is not comparable to the 2014–15 NATSISS. The findings showed that lifetime risky drinking of Indigenous Australians aged 15 and over was similar to that of non-Indigenous Australians (9.8% compared with 9.7%; age-standardised) [5] (Table S3.7). 

Single occasion risk

  • According to the 2014–15 NATSISS, 30% of Indigenous Australians aged 15 and over exceeded the single occasion risk guidelines for alcohol consumption (non age-standardised proportions), which is a decline since 2002 (35%).
  • Comparisons between Indigenous and non-Indigenous Australians are only available using age-standardised data from the 2012–13 AATSIHS and is not comparable to the 2014–15 NATSISS. The 2012–13 AATSIHS reported that 1 in 2 (50%) Indigenous Australians exceed the single occasion risky drinking guidelines (more than 4 standard drinks on a single occasion in past year). This was 1.1 times the rate that non-Indigenous Australians (44%) that exceeded these guidelines [5] (Table S3.7).

Risky alcohol consumption

  • According to the 2016 NDSHS, almost 1 in 5 Indigenous Australians (18.8%) consumed 11 or more standard drinks at least once a month. This was 2.8 times the rate that non-Indigenous Australians (6.8%) consumed this amount of alcohol [7] (Table S3.1).

Geographic trends

Between 2002 and 2014–15 there was a decline in the proportion of Indigenous Australians that resided in New South Wales Victoria, Queensland, South Australia, Western Australia and the Australian Capital Territory that exceeded the lifetime and single occasion risk guidelines (Figure ATSI2). Indigenous Australians residing in Tasmania (36%), the Australian Capital Territory (ACT) (35%), Queensland (33%) and Western Australia (33%) had higher rates of exceeding the single occasion drinking guidelines than the national average [4] (Table S3.8).

Indigenous Australians residing in Western Australia (16%), New South Wales (16%) and Queensland (15%) surpassed the national average for exceeding lifetime risk guidelines [4] (Table S3.9).

Illicit drug use

In the 2014–15 NATSISS, Aboriginal and Torres Strait Islander people aged 15 and over were asked whether they had used illicit substances in the last 12 months, and the types of illicit substances they had used during that period [4]. The data showed that:

  • Almost one-third (30%) of Indigenous Australians aged 15 and over reported having used illicit substances in the last 12 months, up from 22% in 2008.
  • Males were significantly more likely than females to have used illicit substances (34% compared with 27%), as were people in non-remote areas compared with those in remote areas (33% compared with 21%).
  • Cannabis was the most commonly reported illicit drug used by Aboriginal and Torres Strait Islander people in the last 12 months at 19% (25% of males compared with 14% of females).
  • The non-medical use of analgesics and sedatives (such as painkillers, sleeping pills and tranquilisers) was also relatively common (13%), with females (15%) being more likely than males (11%) to have used analgesics and sedatives.
  • One in twenty (5%) Indigenous Australians aged 15 and over reported having used amphetamines or speed in the last 12 months (6% of males compared with 3% of females) [4] (Figure ATSI3).

The 2016 NDSHS data showed that (other than ecstasy and cocaine), Indigenous Australians aged 14 and over recent used of illicit drugs was at a higher rate than non-Indigenous Australians (Table S3.1). Rates of illicit drug use in 2016 for Indigenous Australians aged 14 and older were:

  • Over one in four (27%) used any illicit drug in the last 12 months—1.8 times higher than non-Indigenous Australians (15.3%)  
  • One in five (19.4%) used cannabis in the last 12 months—1.9 times higher than non-Indigenous Australians (10.2%)
  • Around one in 10 (10.6%) used a pharmaceutical for non-medical use—2.3 times higher than non-Indigenous Australians (4.6%) [7] (Table S3.1)
  • 3.1% used meth/amphetamines in the last 12 months—2.2 times higher than non-Indigenous Australians (1.4%).

The differences between Indigenous and non-Indigenous Australians were still apparent even after adjusting for differences in age structure (Figure ATSI4). There were no significant changes in illicit use of drugs among Indigenous Australians between 2013 and 2016, however due to the small sample sizes for Indigenous Australians, the estimates of the NDSHS should be interpreted with caution.

Geographic trends

Indigenous Australians aged 15 and over residing in the Northern Territory (22%) were the least likely to report substance use, while those from the Australian Capital Territory (41%) and Victoria (40%) were the most likely to report using substances.

Indigenous Australians from the Northern Territory (22%) and Queensland (29%) were the only jurisdictions below the national average (30%) [4] (Table S3.3).

Health and harms

Almost 1 in 2 Indigenous Australians with a mental health condition were daily smokers (46%) and about 2 in 5 (39%) have used substances in the last 12 months. This was higher than for Indigenous  Australians with other long-term health conditions (33% and 24%, respectively) or those with no long term health condition (39% and 29% respectively) [4] (Table S3.11).

The Australian Burden of Disease Study provides an indication of the risk factors that contribute to the health gap between Indigenous and non-Indigenous Australians. In 2011, tobacco use accounted for 23.3% of the gap, and alcohol and drug use contributed to 8.1% and 4.1% of the gap, respectively [8] (Table S3.12).

The Penington Institute’s annual overdose report highlights that the rate per capita of drug-related deaths per 100,000 population was almost 3 times higher for Indigenous Australians then non-Indigenous Australians (22.7 compared with 8.2). Specifically across all drug types, Indigenous Australians have a higher rate per capita than non-Indigenous Australians of accidental drug-related deaths. Note, these data are reported for New South Wales, Queensland, Western Australia, South Australia and the Northern Territory only, which are considered to have adequate levels of Indigenous identification in the mortality data [12]. Refer to Box IMPACT1 for different data sources on drug deaths.

Treatment

In 2016–17, the Alcohol and Other Drug Treatment Services National Minimum Dataset (AODTS-NMDS) showed that 15% of clients were Indigenous Australians aged 10 and over (Table S3.13). Indigenous Australians (3,313 per 100,000 population) were 7 times more likely to receive AOD treatment services than non-Indigenous Australians (430 per 100,000 population) were. Specifically where:

  • Amphetamines was the principal drug of concern, Indigenous Australians (1,204 per 100,000 population) compared with 155 per 100,000 population for non-Indigenous Australians.
  • Heroin was the principal drug of concern Indigenous Australians (911 per 100,000 population) compared with 123 per 100,000 for non-Indigenous Australians.
  • Cannabis was the principal drug of concern Indigenous Australians (867 per 100,000 population) compared with 126 per 100,000 for non-Indigenous Australians.
  • Alcohol was the principal drug of concern Indigenous Australians (136 per 100,000 population) compared with 26 per 100,000 population for non-Indigenous Australians [9] (Table S3.14).

Dependence on opioid drugs (including codeine, heroin and oxycodone) can be treated with pharmacotherapy therapy using substitute drugs such as methadone or buprenorphine. The National Opioid Pharmacotherapy Statistics Annual Data collection (NOPSAD) provides information on clients receiving opioid pharmacotherapy treatment on a snapshot day each year. For jurisdictions where data was provided, in 2017:

  • Indigenous Australians were almost 3 times as likely (70 clients per 10,000 population) to receive pharmacotherapy treatment as non-Indigenous Australians (26 clients per 10,000 population) [13] (Table S3.15).

Data from the OSR show that in 2016–17, there were 80 organisations around Australia that provided alcohol and other drug treatment services to around 39,400 Aboriginal and Torres Strait Islander clients [10]. The OSR data also shows that:

  • All 80 organisations reported that alcohol was one of the top five common substance-use issue, followed by cannabis (95%) and amphetamines (80%)
  • Treatment episodes were more likely to occur in non-residential settings (89%)
  • One quarter of all treatment episodes were in Very remote areas (24%) and the highest proportion of clients were located in Major cities (37%). 

Policy context

The Aboriginal and Torres Strait Islander Health Performance Framework 2017

The Aboriginal and Torres Strait Islander Health Performance Framework 2017 includes a suite of products that give the latest information on how Aboriginal and Torres Strait Islander people in Australia are faring according to a range of 68 performance measures across 3 tiers: Tier 1—health status and outcomes, Tier 2—determinants of health, and Tier 3—health system performance. The measures are based on the Aboriginal and Torres Strait Islander Health Performance Framework and cover data that has been collected on the entire health system, including Indigenous-specific services and programs, and mainstream services [12].

National Aboriginal Torres Strait Islander Peoples Drug Strategy 2014–2019

The National Aboriginal and Torres Strait Islander Peoples’ Drug Strategy 2014–2019 was a sub-strategy of the National Drug Strategy 2010–2015 and remains a sub-strategy under the National Drug Strategy 2017–2025. The overarching goal of this sub-strategy is to improve the health and wellbeing of Aboriginal and Torres Strait Islander people by preventing and reducing the harmful effects of alcohol and other drugs (AOD) on individuals, families and their communities [15].
