Method
Between 6 June and 9 June 2023, The Australia Institute surveyed 1,002 adults living in
Australia, online through Dynata’s panel, with nationally representative samples by gender,
age group and state/territory.
Voting crosstabs show voting intentions for the House of Representatives. Those who were
undecided were asked which way they were leaning; these leanings are included in voting
intention crosstabs.
The research is compliant with the Australian Polling Council Quality Mark standards. The
long methodology disclosure statement follows.
Long disclosure statement
The results were weighted by three variables (gender, age group, and state or territory)
based on Australian Bureau of Statistics
“National, state and territory population”
using the raking method. Those who answered the gender identity question as “Non
-
binary”, “I use a different term”, or “Prefer not to answer”
, had their responses included
with females for the purpose of reporting, due to constraints from weighting data
availability. This resulted in an effective sample size of 943.
The margin of error (95% confidence level) for the national results is ±3%.
Results are shown only for larger states.
Voting intention questions appeared just after the initial demographic questions, before
policy questions. Respondents who answered “Don’t know / Not sure” for voting intention
were then asked a leaning question; these leanings are included in voting intention
crosstabs. “Coalition” includes separate responses for Liberal and National. “Other” refers to
Independent/Other, and minor parties in cases where they were included in the voting
intention but represent too small a sample to be reported separately in the crosstabs.
