More than 300 First Nations advocates and campaigners from every state and territory are meeting in Meanjin (Brisbane) Thursday and Friday to build movements for justice and self-determination.

Organisers of the Common Threads Summit say the two-day event has been designed "by and for First Nations people" as an opportunity to build collaborations across a range of issues, organisations and communities.

Summit keynote speaker, Bidjara, Birri-Gubba and Juru woman Dr Jackie Huggins AM FAHA, said the movement is building support for "transformative change that centres the demands our communities have been fighting for over generations - like stopping Black deaths in custody, land rights, climate justice, treaties, truth-telling and representation".

Bundjalung woman and First Nations Justice Director at Australian Progress, Amelia Telford, said building relationships is "the first step to building power".

"Common Threads is about connecting First Nations advocates and organisers working across a breadth of issues, organisations and regions," she said.

Get Up chief executive and Widjabul Wia-bal woman from Bundjalung Country Larissa Baldwin-Roberts said 2023 is a "defining year for First Nations justice and self-determination".

"In the next two days we'll be having important conversations, sharing skills and building strategies that will deliver transformational change," she said.

The Summit features workshops, case studies and guest speakers on six issue streams: law reform and transformative justice; protecting country, climate and cultural heritage; racism and inequality; organising in First Nations communities for and beyond the referendum; reclaiming education and long term planning for Truth, Treaties and representation.

Speakers include Aunty Mary Graham, Aunty June Riemer, Apryl Day, Danny Billy, Melissa Lucashenko, Rachel Perkins, Megan Davis, Tarneen Onus-Browne, Anyupa Butcher and Bo Spearim.

Common Threads is a project of Passing the Message Stick, led by a steering committee of Dr Huggins AM, Ms Baldwin-Roberts and Ms Telford, and delivered through a partnership between GetUp and Australian Progress, with support of organisations including Dhadjowa Foundation and Jumbunna Institute.
