National Health Survey
The Australia-wide 2020-2021 National Health Survey (ABS 2022) conducted by the Australian Bureau of Statistics (ABS), collected a range of information about the health of Australians including their use of health services such as consultations with dentists or other dental professionals. The data presented in this section were sourced from this survey.
Box 1: National Health Survey 2020–21
Data for 2020–21 are based on information self-reported by the participants of the Australian Bureau of Statistics (ABS) 2020–21 National Health Survey (NHS).
Previous versions of the NHS have primarily been administered by trained ABS interviewers and were conducted face-to-face. The 2020–21 NHS was conducted during the COVID-19 pandemic. To maintain the safety of survey respondents and ABS Interviewers, the survey was collected via online, self-completed forms.
Non-response is usually reduced through interviewer follow-up of households who have not responded. As this was not possible during lockdown periods, there were lower response rates than previous NHS cycles, which impacted sample representativeness for some sub-populations.
Additionally, the impact of COVID-19 and lockdowns might also have had direct or indirect impacts on people’s usual behaviour over the 2020–21 period, and the module used to collect information on physical activity was changed as part of the NHS 2020–21.
Due to these changes, comparisons to previous National Health Survey data over time are not recommended.

Box 2: National Health Survey 2020–21 definitions
Alcohol consumption
The National Health and Medical Research Council (NHMRC) released Australian guidelines to reduce health risks from drinking alcohol in December 2020. Guideline 1 recommends that ‘to reduce the risk of harm from alcohol-related disease or injury, healthy men and women should drink no more than 10 standard drinks a week and no more than 4 standard drinks on any one day’. In the National Health Survey 2020-2021, exceeding the guidelines is interpreted as consuming more than 10 standard drinks in the week prior to survey, or consuming 5 or more standard drinks on any day in the last year at least monthly, or exceeding both components.
Smoker status
Smoker status refers to the frequency of smoking of tobacco, including manufactured (packet) cigarettes, roll-your-own cigarettes, cigars and pipes. In the National Health Survey 2020-21, respondents were categorised as:
- Current smoker – a respondent who smoked cigarettes, cigars or pipes
- Ex-smoker – a respondent who does not smoke currently, but previously smoked daily, or has smoked at least 100 cigarettes, or smoked pipes or cigars at least 20 times in their lifetime
- Never smoked – a respondent who has never regularly smoked daily, and has smoked less than 100 cigarettes, or smoked less than 20 pipes or cigars in their lifetime.
In 2020–21, 1 in 2 (48%) Australians had consulted a dentist or dental professional in the last 12 months
In 2020–21, according to self-reported data, the proportion of people who had consulted a dentist or dental professional in the last 12 months was:
- higher for females (52%) than males (45%)
- similar for those who exceeded lifetime risk alcohol consumption guidelines (49%) than those who did not exceed guidelines (47%)
- lower for current smokers (39%) than those who have never smoked (48%).
