An Indigenous women's rugby league team is calling for support as they prepare to take their talents overseas for the first time.

The Murri Gummaz, a team of Aboriginal and Torres Strait Islander women and girls, has been undefeated for three consecutive years at the Queensland Murri Carnival and Mackay All Blacks Carnival.

Now, they've been invited by Samoa NRL to compete internationally with both junior and women's squads.

Gungarri and Wulgurukaba woman and team co-director Ms Sharnee Hegarty said the invitation followed several years of grassroots success.

"Our girls have come from all over - the NT, WA, Torres Strait, Sherberg, Redfern, Kempsey - and still come together and play like they've trained all year," Ms Hegarty told National Indigenous Times.

Despite their achievements, the team faces major funding barriers.

"We don't fit the criteria for government support," she said.

"We're not a charity or an incorporated organisation. But we are a strong community," she said.

Ms Hegarty said the trip was about more than sport.

"This is a legacy trip, there's never been a young women's or women's team from Australia to play in Samoa," she said.

"It's about cultural exchange, leadership, and showing the strength of our girls."

Some players will need to apply for passports and birth certificates for the first time.

"Some of these girls have never left Queensland, let alone Australia," Ms Hegarty said.

Funds raised will cover travel costs for 45 players and staff to travel to Samoa in September.

The group plans to visit both Upolu and Savai'i islands, with cultural ceremonies and exchanges planned with local Samoan communities.

"Our girls are preparing dances, songs and gifts," she said.

"We've got cultural advisors supporting us to make sure it's done right - from Aboriginal, Torres Strait and Samoan perspectives."

To support the trip, the Murri Gummaz have launched a GoFundMe and are hosting a major fundraising gala on 5 July at Witten Barracks in Indooroopilly.

They are also running raffles and community events, including a charity touch game in partnership with Flight Centre on 30 May at Musgrave.

Donations from the community and small businesses have already begun to flow, including items from artists and performers.

Ms Hegarty said that while the support from mob has been overwhelming, major corporate support is still needed.

"We're grateful for every bit we receive," she said.

"But what we really need now is big sponsors - the banks, airlines, corporates with RAPs.

"We need them to get behind this."

Ms Hegarty said they had been overlooked by some donors reluctant to support Indigenous-led initiatives.

"People say 'now's not the right time' because of the political climate," she said.

"But this isn't about politics -it's about backing incredible young women doing something positive.

"Our girls aren't 'at risk'. They're already strong. They're already leaders. They just need the chance to show it."
