A new summer exhibition exploring the creation story of the Bundjalung Nation is set to open at Tweed Regional Museum this week.

Titled 'The Wiiyaan,' the exhibition, opening Friday, presents the Bundjalung creation story of the Three Brothers and traces the origins of the Nation's tribes and dialects through contemporary cultural practice.

The exhibition has been developed through the work of Gudjingburra Bundjalung men Kyle and Bijang Slabb with digital support from Ludo Studios.

The Wiiyaan refers to the unbroken ancestral line of the Tweed Bundjalung people and centres on the Three Brothers creation story, which explains how Bundjalung tribes and dialects came to be.

The story tells of three brothers who travelled across the sea in a canoe and settled in the region before separating and moving north, west and south.

In the southern dialect, the brothers are known as Mamoon, Birrung and Yar-Birrain, while in the northern dialect they are called Yarbiri, Marming and Birin.

Their movement across Country led to the formation of distinct tribes and the development of different dialects, with key parts of the story marked by natural landmarks across the Northern Rivers.

Mr Slabb said the exhibition is grounded in the responsibility of passing knowledge to younger generations.

"One of the considerations that we have to think about now and the time that we're in is what we pass on to the next generation," he said.

"We're the last generation of contact with traditionals in our community... our kids' generation never knew our grandmothers and our grandfathers."

Mr Slabb said the risk of cultural loss during this transition made active knowledge transfer essential.

"During that transition for a community, what doesn't get passed on, you can lose so it's important that we have a lot of transfer of knowledge in this generation," he said.

Mr Slabb said the project was created to ensure Bundjalung children grow up with a clear understanding of their origins.

"This project is part of that exercise for me, that every Bundjalung kid should know our origin story," he said.

"They should know what connects back to our Bundjalung law.... they should have an understanding of that."

The exhibition draws on digital and material illustrations developed by the local Tweed Aboriginal community over several years.

These works were created as teaching tools and shared with Elders and knowledge holders to support the transfer of lore to younger generations.

The Wiiyaan opens on 9 January 2026 and will run at Tweed Regional Museum until 18 July 2026.
