Online gambling in Australia snapshot: methodology

The ACMA annual consumer survey provides insights into:

• consumer behaviour
• adoption of, and attitudes towards, media and communications services
• the effectiveness of regulatory interventions.

This research is part of the ACMA research program, which gathers evidence that informs our decisions as a regulator, and ensures we are up-to-date on market developments and consumer trends.

From 2017 to 2021, the ACMA-commissioned research was undertaken by The Social Research Centre (SRC) using the SRC’s probability-based online panel, Life in Australia (LinA). While most respondents completed the survey online, LinA also included people without internet access or who are not comfortable completing surveys online, who completed the survey by phone.

The survey data is representative of the Australian population aged 18 and over.

Note: The 2021 total sample size was increased to enable more robust analysis of smaller survey subgroups.  

Table 2: Sample profile of respondents who completed the surveys (unweighted), 2017 to 2021

Note: ‘Metropolitan’ refers to those who live in Australian capital cities and ‘Regional’ refers to those who live in the rest of the state, as defined by the Australian Bureau of Statistics’ (ABS) Greater Capital City Statistical Area definition.

The table below details the changes to the ACMA annual consumer survey questions referenced in the Online gambling in Australia snapshot. These changes should be considered when interpreting findings.

The Online gambling in Australia snapshot presents the key findings and trends across the surveys conducted from 2017 to 2021.

• All percentages are based on weighted survey estimates.
• All percentages are rounded to the nearest whole number. As a result, there may be discrepancies between sums of the component items in a table or chart, and the total.
• Base sizes are shown as the unweighted number of respondents on which the weighted estimates and proportions are based.
• Categories with low sample sizes (less than n=100 interviews) should be interpreted with caution.  
• Terminology of ‘use of an activity’ in key findings refers to measuring prevalence of an activity being undertaken (that is, the proportion of the population who have undertaken activity at all in the relevant time period), rather than frequency (unless stated).
• All key findings highlight results that have been tested for statistical significance at the 95% confidence level.
• The ACMA annual consumer survey research:
  • The research often asked about ‘the past 6 months’ – this is the period before the data was collected. For the 2021 survey, this broadly represents the period from December 2020 to June 2021.
  • Included some questions that have been filtered depending on the respondent’s previous responses (for example, the question about which internet activities were undertaken was only asked of those who reported in an earlier question that they had undertaken an internet activity in the 6 months before the survey). This is noted in descriptive language in the chart’s ‘base’ notes and the corresponding methodology tables. Care needs to be taken when interpreting the results so that the data is read in the correct context.
  • Included some questions that invited a multiple response, so the total responses may sum to more than 100%.
