Smoking prevalence varies across Australian states and territories; however, it is important to note that estimates of prevalence in each state and territory may be less reliable than those for the total population.
1.13.1 Latest estimates of prevalence in Australian states and territories
Table 1.14.1 sets out estimates for prevalence of smoking, ex-smoking and never smoking in each state and territory in among Australians 14 years and older from the 2019 National Drug Strategy Household survey.1
Prevalence of daily, regular and current smoking* for Australians 14+ by sex, 2019, in each state and territory and Australia (age standardized)
*Includes persons smoking any combination of cigarettes (factory-made and roll-your-own), pipes or cigars
† Smoked more than 100 cigarettes (manufactured or roll-your own) or the equivalent amount of tobacco in their life but reports no longer smoking.
‡Never smoked more than 100 cigarettes (manufactured or roll-your own) or the equivalent amount of tobacco.
^ Estimate has a relative standard error of 25% to 50% and should be used with caution.

National Health Survey
The Australian Bureau of Statistics’ National Health Survey also provides data on smoking prevalence for each state and territory in 2014–15 and again in 2017–18, see Table 1.13.2. Note data is for Australians 18 and over whereas the data above from the NDSHS is for Australians 14 and over.

1.13.2 Trends in prevalence in Australian states and territories
To assess changes over time in in the prevalence of regular smoking (daily plus weekly) for Australians 18+ between states, data from the National Drug Strategy Household Survey for people aged 18 years and over were weighted to the Australian population appropriate for each survey year and examined by state. (Data for regular smoking for 2019 will be obtained and added once the data-file becomes available.) As shown in Figure 1.13.1, since 2001, adults in the Northern Territory (NT) have consistently had the highest level of regular smoking among those aged 18+ years (20% in 2016). In 2016, residents of NT were significantly more likely to be regular smokers than people from any other state except Tasmania and Queensland (controlling for age and sex). High smoking rates in the NT may reflect the high percentage of Indigenous Australians residing there—smoking rates among all Indigenous Australians were about 39% in 2014–152 —see Section 8.3. About 26% of the residents of the NT are of Aboriginal and Torres Strait Island origin, compared with 5% or less in all other states and territories.3
Prevalence of regular* smoking, † Australians aged 18+, 2001–16—by each Australian state and territory
* Includes those reporting that they smoke ‘daily’ or ‘at least weekly’.
† Includes persons smoking any combination of cigarettes, pipes or cigars.
‡ All data weighted to the Australian population appropriate for each survey year and may vary slightly from data presented in previous edition

Significant linear declines in adult regular smoking prevalence from 2001 to 2016 have been observed in all states and territories (controlling for age and sex). For the period of 2013 to 2016, there were no significant declines in smoking prevalence in any state or territory.
