Australia's peak body for Indigenous children is establishing a 'Youth Voice' to give First Nations children and young people a platform to inform policies and programs that impact them.

SNAICC – National Voice for Our Children said on Monday the Youth Voice would provide a mechanism for young Indigenous children to shape and contribute to SNAICC's work in a "safe, supported and reciprocal environment".

Chief executive Catherine Liddle said as experts in their environment and experiences, young people must be heard by people who make decisions on their behalf.

"The decisions made by SNAICC, governments, and the sector today will shape the future for our children," the Arrernte/Luritja woman said.

"The voices of our young people must be at the centre of that process."

She said SNAICC wanted the platform to be "reciprocal," giving both parties the tools and skills to be leaders and enact meaningful change, both in their communities and at a national level.

"While the direction and priorities of the Youth Voice will be informed by its members, we anticipate its work will help identify key policy, advocacy, and program priorities," Ms Liddle said.

"It will also provide feedback on projects and programs and guide SNAICC's advocacy to ensure it reflects what truly matters to Aboriginal and Torres Strait Islander young people."

The announcement comes after the government launched a National Commissioner for Aboriginal and Torres Strait Islander Children and Young People in January, with Ngemba woman Lil Gordon taking the reins in an interim role.

It has the power to investigate and tackle the serious issues impacting First Nations children, including the over-representation of Aboriginal and Torres Strait Islander children in out-of-home care (OOHC), and was lauded as a "major milestone" for Indigenous children by SNAICC at the time of the announcement.

Indigenous children are removed from their families at 10.4 times the rate than non-Indigenous children, whilst Indigenous children between the ages of 10 and 13 are imprisoned 45.5 times the rate of their non-Indigenous cohort.

SNAICC says the new Youth Voice - currently in its design phase - will see the peak body engaging with Aboriginal community-controlled organisations (ACCOs) and other stakeholders, as well as in "youth-specific consultations", to understand how the model can "best reflect the communities in which our young people live".

The organisation is inviting Aboriginal and Torres Strait Islander young people, youth groups, communities, organisations and services to help shape the Youth Voice by making a private submission, which can be made in writing or through other formats like audio, video or artwork.

Ms Liddle said SNAICC advocates for change at all levels of government to make sure Indigenous children and young people "grow up healthy, strong, and connected to culture and community".

"Our incredible young people must be part of and guide that journey," Ms Liddle said.
