Former professional boxer and Bundjalung man Anthony Mundine has threatened to "bring a group of brothers" and "raise hell" if Prime Minister Anthony Albanese visits a Sydney mosque again.

Mr Albanese visited western Sydney's Lakemba Mosque to meet with members of the Muslim community and promote the Voice to Parliament referendum on Friday.

Following the visit, the former champion Indigenous boxer turned to social media, slamming the prime minister for "pushing new world order s***," whilst claiming the Voice would "enslave humanity".

"Listen I've f***king had enough, they're bringing the prime minister to the place of worship, the mosque, and pushing this 'Yes' s***," Mr Mundine said in the video.

"Pushing you, asking you, to go and give yourself, and enslave humanity, and enslave the people, asking you to push this new world order s***."

Mr Mundine recently declared his support for the No campaign, joining his second cousin, prominent No campaigner Nyunggai Warren Mundine, and Northern Territory senator and Shadow Minister for Indigenous Australians, Jacinta Nampijinpa Price, in opposition to the Voice.

Mr Mundine converted to Islam in the '90s.

"If he comes to the mosque, wallahi, wallahi, I'll bring a group of brothers and we're gonna f***ing raise hell. "It's on now, it's f***ing on," he said.

Australian Muslim community leaders recently declared their support for the Voice, asking Australian mosques to dedicate their Friday sermons in support of the Yes vote.

Their support coincided with Mr Albanese's visit, making him the third prime minister to visit Lakemba Mosque.

On Instagram, Mr Mundine conveyed his disappointment in Islamic leaders supporting the Voice.

"Pushing this yes vote, with the prime minister that supports Israel, we should be opposing everything they do, because they've done nothing for us Muslims or us Black fellas," he said.

"They want to give us a voice, a so called voice that's smoke and mirrors for something else, another agenda, to take our freedoms and our liberties, to take our land, it's the biggest land grab of all time."

In the video captioned "what you gonna do, stand up or shut up", he also berated Mr Albanese's support of Israel following the recent dramatic escalation of violence in the country and Gaza, whilst voicing his support for Palestine.

"He backs Israel, and the Jews, America, Britain, like France, they all back them, all the superpowers," Mr Mundine said.
