Key polling companies are YouGov, Essential Media Communications, Roy Morgan Research, and Resolve Strategic.
Ipsos polls used to be published in The Sydney Morning Herald, The Age and the Australian Financial Review;[1][2] however following the shock result of the 2019 Australian federal election, when the Coalition won the election against all of the opinion polls' predictions, the Nine Entertainment group decided to discontinue its relationship with that company.
Post-election, several well-known psephologists undertook assessments of accuracy for the voting results produced by each major pollster’s final poll.
These employed differing methods of assessment, but generally determined that the polling industry was more accurate overall than in 2019, though still tended to overstate Labor’s primary vote share.
However, there was a collective error in favour of Labor, whose actual primary vote came in 2.3% below the pollster consensus while the Coalition landed 0.4% higher”.
