The Indigenous production company behind ABC series Redfern Now has slammed Anthony Mundine's comments that Aboriginality and homosexuality do not mix.

Mundine posted on Facebook last night that promoting homosexuality in Aboriginal culture is not OK and Indigenous ancestors would have someone's head for it.

The first episode of the show's second series centred around a gay Indigenous man who had to fight his deceased partner's mother for custody of his daughter following a fatal accident.

But Mundine, who converted to Islam, said his father told him that God created Adam and Eve, not "Adam and Steve".

"Watching redfern now & they promoting homosexuality! (Like it's ok in our culture) that ain't in our culture & our ancestors would have there head for it! Like my dad told me GOD made ADAM & EVE not Adam & Steve."

Mundine goes on to post that he has nothing against homosexuality because he has friends and family that are gay, but says it should not be promoted to youth and the masses.

Indigenous actor Luke Carroll, who appeared in the first season of Redfern Now as the character Lenny, also weighed into the debate saying "God and Christianity" are not a part of Indigenous culture.

Carroll: "God or Christianity isn't apart of our Culture either... our Ancestors had dreamtime beliefs!" Mundine: "Luke Carroll yu serious bra? Yu know that shit wouldn't fly back in the day...your off ya head!" "I got nothing against it cause I got friends family that are but promoting it to the youth & masses isn't right... but each to there own." Carroll: "I'm talking about all these blackfullas that have been brainwashed with Christianity & a belief in this 'White Jesus' who is their saviour!! These beliefs where brought over by the white man on the first fleet!! In regards to homosexuality... well I'm with you on that one, each to their own."

Rachel Perkins, whose production company Blackfella Films is behind the series, says the comments are deeply upsetting and wrong.

"I've known Aboriginal activists throughout the '60s and '70s and '80s and '90s who fought for the cause of Aboriginal people and they are gay," she said.

"[Mundine] saying gay people and Aboriginality don't go together denies all of the identity of those people. It's insulting to them - it's inappropriate that he says that."

Perkins says last night's episode was not promoting homosexuality but dealing with the issue of same-sex couples who want the right to have children.

"It's about love, it's about parenting. You know we're not pushing some "you know everyone has to be gay" to young people - that's just totally misreading the program," she said.

"He should have more intelligence to see it what it is. It's a story about people."

'Narrow minded and uneducated'

Mundine's post attracted more than 90 "likes". Among them was his cousin Blake Ferguson, who caused controversy with social media during his time at the Canberra Raiders.

However, while the post did receive support, others hit back saying Mundine was wrong.

One woman, Steph Broome, who said she is both Indigenous and a lesbian, wrote that she felt embarrassed for Mundine.

"I must say it's really sad to see such a comment from an Aboriginal sporting star who might I add is a narrow minded, uneducated human being," she said.

"Love is free, and people should be free to love who they love without judgement."

Another commenter Amanda Fischer also took exception to Mundine's post.

"People listen to what u say and I understand it wasn't a belief of our ancestors but u cry racism whn u are discriminating against homosexuals who in today's world deserve the same right as u me or the next person," she said.
