In footage obtained by The Daily Telegraph, after Mundine's emotional exit from the Channel Ten reality show, the 42-year-old claims he wants capital punishment for the gay community.
Mundine revealed homosexuality, banned in Islam, was also shunned in Aboriginal culture.
“If we were to live in a society, just like in Aboriginal culture, that homosexuality is forbidden and you do it and the consequences are capital punishment or death, you think you are going to do it? Or think twice about doing it?”
"That's the only way to deter the problem," he continued.
Mundine also said that paedophiles should face similar punishments.
"Hang them suckers," he said, but clarified he was referring to "the paedophiles mainly".
But the controversy did not stop there, the star also claimed that gay rights could be connected to the possible legalisation of paedophilia.
"Because they are pushing these gay rights so much in the Western world, the paedophiles out there want their rights.
"Now they are going to claim to have rights. They want their rights just like the gay people want their rights."
Following his crude comments, Twitter users have taken to the platform to express their disagreements with the athlete's views.
