A man has tried to sell his same-sex marriage vote for over a thousand dollars.
The Sydney man was busted auctioning his vote for $1663 on eBay.
Listed as 'Buy my vote" the seller said he had no desire to fill out the form, and wanted to sell his vote because he doesn't care.
"The reason I'm selling my vote is because I don't care either way but thought there are people who do".
He also wrote that part of the auction proceeds would go to kids battling cancer.
Seven News reported that Australians for Equality campaign executive director Tiernan Brady and Australian Christian Lobby managing director Lyle Sheton said the seller needed to take the vote more seriously.
"What an idiot. What do you think you're doing? This is a serious discussion about real people's lives", Mr Tiernan told ABC.
Mr Shelton said it "really does trivialise what is a very important decision for the Australian nation".
The Australian Bureau of Statistics (ABS) has been in touch with a number of websites, including eBay, Facebook and Amazon with concerns.
A spokesman from ABS said eBay and Facebook have confirmed they would block and remove listings that did not comply with the sites' policies.
A maximum penalty of $2100 or a 12-month jail sentence would be imposed on people buying or selling responses to the vote.
