As First Nations Matildas Lydia Williams and Kyah Simon prepare for their FIFA Women's World Cup campaigns, Australia's first recognised Indigenous man to represent the nation says not enough is being done to see more mob join them.

John Moriarty first pulled on the Green and Gold in over sixty years ago.

In the time since only a handful have followed in his footsteps.

The Yanyuwa man ties the lack of funding into Indigenous football and remote communities as a contributor to why.

On Wednesday his John Moriarty Foundation announced a public-funded campaign to fill the gaps missed by the sport's governing body.

The mission is to "address the lack of Indigenous football players at the elite levels of the game, and raise funds to tackle the disparity they face".

Football Australia says Legacy 23 locks into the representation and growth of women in the game.

State and federal governments have chipped-in on the cause.

JMF engages with Indigenous boys and girls, communities and schools to strengthen representation at the elite level alongside wider life benefit - to break "the cycle of disadvantage".

The foundation says they have seen "no evidence of funding for grassroots Indigenous football programs to increase participation, ensure equitable access to the game or create meaningful social change" from Legacy 23.

With GoFundMe, JMF have launched the 'Indigenous footballers call time on inequality' initiative.

"The Women's World Cup presents a once-in-a-generation opportunity to create a legacy for Indigenous football in Australia and invest in solutions that will result in exponential social change and ensure equitable access to football for grassroots and elite Indigenous players," Moriarty said.

"Indigenous players have to fight that much harder just to have the same opportunities as non-Indigenous players and those living in remote and regional communities also face extreme financial disadvantage, high unemployment and housing challenges. Yet we know how much talent these Indigenous footballers have.

"Football has the power to be a game-changer for Indigenous children and their communities. These children have the passion and the drive. Now is the time to level the playing field by reaching even more children, more communities and empowering the next generation of Indigenous football players.

"There needs to be increased investment in solutions that will lead to impactful social change and ensure equal access to football for both grassroots and elite Indigenous players."

GoFundMe regional director Nicola Britton said she has seen how grassroots-led programs have serious impact in closing the health and wealth for Indigenous Australians.

Their collective goal sits as $100,000.
