Sydney man who joked about binning 'no' votes cops death threats

A Sydney man who joked about being an Australia Post worker and binning “no” same sex marriage votes has received death threats.

The threats came after social media users took to Facebook earlier this week to air their concerns that responses to the same-sex marriage survey could be tampered with.

The Facebook posts showed pictures of people shining a torches over the reply-paid envelope included with the survey to reveal which box had been ticked within.

In response to the posts, Sydney man Dan Nolan posted this tweet:

Australia Post has since confirmed Mr Nolan does not work for them.

But not before the jokester copped the brunt of some angry abuse.

A spokesperson for Matthias Cormann, Acting Special Minister of State, told the ABC that Australia Post would have extra security measures in place to make sure no votes were tampered with.

"Australia Post are also working closely with the authorities to maintain the integrity of the mail network," she said.

The ABS started sending out same-sex marriage surveys on Tuesday, and expects to have all forms mailed out by September 25.

All forms must be completed and returned by November 7.
