The godson of former Australian Prime Minister Kevin Rudd has been bashed after standing up for marriage equality.
The country is in the midst of a postal survey designed to gauge public interest in allowing same-sex marriage.
A majority result of yes to the same-sex marriage vote could encourage MPs to move towards a law change.
The two-time Labor Prime Minister tweeted the picture of his godson, standing blooding on a bus stop, who Mr Rudd says was attacked while campaigning for same-sex marriage legalisation.
"So many warnings to Turnbull about what the postal vote could unleash. Now my godson Sean has been punched for standing up for marriage equality."
Voting packs are being sent out across the country over the next few days, in what is proving to be a highly controversial debate.
