In 2017 Cory Bernardi, an Australian conservative politician, accidentally ended up in a photoshoot organized by the Labor party to promote voting yes to the question "Should the law be changed to allow same-sex couples to marry?" in the same-sex marriage postal survey.

The survey had a turnout of 79.5% and the results were:

yes: 61.6%
no: 38.4%

As a result of the survey parliament was able to vote and legalize same-sex marriage. The survey results happened in November 2017 and same-sex marriage was legalized in December 2017.

Bernardi accidentally walked through the marriage equality photo of Western Australia Labor politicians wearing rainbow "It's Time" shirts in Parliament House on Monday night.

Bernardi is firmly against legalising same-sex marriage and is campaigning for the "no" camp in the same-sex marriage postal survey.
