Fight organisers have said they will not play the Australian national anthem early to please champion boxer Anthony Mundine, who has threatened to sit down during the song.

The firebrand boxer, who will face off with Danny Green on Friday, said he is trying to educate people Advance Australia Fair is a theme song for the white Australia policy, which is unjust to indigenous Australians.

Organiser Steve Crawley said he will continue to speak with Mundine's agent Khoder Nasser in the next few days, but 'can't see why' they won't have Jessica Mauboy perform while both fighters are in the ring.

'They way I figure it is that if you go to an NRL or AFL grand final, the athletes are on the field when the anthem is performed,' Mr Crawley told The Daily Telegraph.

Anthony Mundine has explained why he won't be standing for the national anthem during Friday night's grudge bout against Danny Green

He said the choice to have Jessica Mauboy sing Advance Australia Fair was 'nothing to do with her being indigenous'.

On Monday in Adelaide, Mundine said he was a man 'that stands against wrong' and believes the national anthem is a 'big wrong in our country'.

''Advance Australia Fair', if you speak to your historians and educated college professors, (it's) fair - as in white fair - not as in fair go,' he told SBS.

'That was the theme song for the white Australia policy, from 1901 to the early 1970s when Aboriginal people weren't even considered citizens.'

The Indigenous boxer, and former rugby league star, also said Jessica Mauboy was chosen to sing the anthem in Adelaide on Friday 'because she is black'.

He called on Mauboy to not go ahead with singing the anthem at the Friday match in Adelaide because 'it's not for our people'.

'They are just using her because she is black,' Mundine told Daily Telegraph.

Mundine said he was not trying to divide Australians but his people are not 'young and free'.

'Who cares what Anthony Mundine is saying?' One Nation Senator Pauline Hanson told Sunrise.

'That is his opinion, but the fact is, we have teachers in schools who are telling kids, children, you don't have to stand for the national anthem. They're saying if you find it offensive, don't stand and leave the classroom.

'We are saying this in our classrooms. Why should we worry about what Anthony Mundine is saying? I am more concerned about what the kids are being taught in our classrooms.'

In a press conference on Monday afternoon, Prime Minister Malcolm Turnbull said he did not agree with Mundine.

'Our national anthem unites all Australians, I don't agree with him.

'From our First Australians, to the newest baby in the arms of a migrant mother.'

'They are just using her because she is black,' Mundine said of Jessica Mauboy (pictured singing carols at The Domain in December last year)

Not the first time: In September, Mundine encouraged NRL and AFL players to boycott the anthem at the grand finals in a Facebook post

At the time Mundine said the national anthem was written when 'blackfullas were considered fauna (animals)'

In September, Mundine encouraged NRL and AFL players to boycott the anthem at the grand finals.

'The anthem was written in late 1700s where blackfullas were considered fauna (animals). Advance Australia Fair as in white not fair as in fair go,' Mundine wrote on Facebook.

'All players aboriginal & non aboriginal should boycott the anthem & start changing Australia's ignorant mentality... lets move forward together yo.'

Former league players Larry Corowa and Joe Williams joined in the call for players to boycott the anthem.

Mr Turnbull criticised the boycott in September, and Today Show host Karl Stefanovic called it 'ridiculous'.

Mundine and Green last competed in 2006, more than 10 years ago.
