A First Nations artist and two Indigenous cricketers have collaborated to design the Sydney Thunder's First Nations kit ahead of the upcoming Big Bash League (BBL) and Women's Big Bash League (WBBL) seasons.

Western Sydney-based Yuin artist, Rheanna Lotter, partnered with Gumbaynggir batter Anika Learoyd and Kamilaroi seamer Hannah Darlington to design the strip titled 'Jaanymili', a Gumbaynggir word meaning gathering, coming together and connecting.

The shirt tells the story of Darlington and Learoyd's journeys, from family, to meeting each other and growing together through cricket.

"It's really special to see our journeys and our culture represented through this design," Darlington said.

"Rheanna has done an amazing job capturing the connection Anika and I share, not just as teammates but as proud First Nations women.

"To wear this shirt is a reminder of where we come from and the people who've helped us along the way."

Darlington's totem Kaputhin (the Eagle) and Learoyd's totem Gaagal (the Ocean) are featured on the back alongside their families.

Learoyd said being part of creating Jaanymili was "such a meaningful experience".

"The design tells a story of coming together - of family, community and cricket - and it's something I'm incredibly proud to wear," she said.

"It's a powerful way to celebrate First Nations culture and what it means to be part of the Thunder family."

While celebrating the club's proud First Nations players, the design also represents all Thunder players, symbolized by the 'U' in the central meeting place.

Lotter has designed Thunder's First Nations kits for community and elite teams since 2016, with this year's design marking the first time she's collaborated with players.

"I really appreciated working with the girls this year," Lotter said.

"They wear it, it's their story and I think they feel a bit more of a connection to it... Exposure is the biggest thing in our culture, so having a design that everybody can see and feel connected to is really important and I think that's only going to start conversations."

The design retains the Thunder's distinctive thunderbolt, which the club says reflects "the energy and power created when players, staff, sponsors, fans, and the wider community come together - united as the Thunder Nation".

The kit is set to be debuted on November 19 as part of Thunder's First Nations Round at Drummoyne Oval, where the club will honour and celebrate Indigenous culture with cultural performances and activities.

The Sydney Thunder First Nations kit t will be available for purchase via the Cricket Australia online shop from Wednesday, November 5.
