An Aboriginal-led alliance is improving wellbeing, education and community connections in communities throughout South Australia's Spencer Gulf.

The Port Augusta and Davenport Community Alliance is responsible for a growing number of initiatives improving safety in the two communities.

It is comprised of Traditional Owners, Aboriginal Community Controlled Organisations, young people and a variety of community stakeholders including community service agencies, police and business representatives.

Following community consultation, the Alliance is now implementing a safety and wellbeing plan, shaped by community.

Support is being offered by both the Commonwealth and South Australian Governments, which are collectively investing $12 million over three years to improve social outcomes in the region, particularly for young people.

Federal Minister for Indigenous Australians, Malarndirri McCarthy, said the Alliance is about community voices being heard and driving real change.

"The Port Augusta and Davenport Community Alliance is a wonderful example of what can be achieved through collaboration and cooperation between governments, communities, Traditional Owners and Aboriginal Community Controlled Organisations," Senator McCarthy said.

"This is a practical example of programs being delivered with the approach set out in the National Agreement on Closing the Gap on formal partnerships and shared decision making."

The impact of the Alliance's work is already being felt across the region.

The government says 545 people have been supported to travel from Port Augusta since July last year, through the Return to Country Program, which continues to expand.

A new after-school hub in the CBD for youth aged 12-17 has also seen strong engagement with over 450 attendances since commencing in Term 1 this year, offering young people a place to connect four days a week.

And young people in Port Augusta also have greater access to safe spaces and support with extended hours at the Aboriginal Youth Centre and through the youth bus service.

Port Augusta and Davenport Community Alliance Group member, Rob Singleton, said the Alliance is making a significant impact throughout Spencer Gulf communities.

"The Alliance allows us to fill service gaps, improve safety, create meaningful opportunities for our young people and families and driving real change," Mr Singleton said.

"This is more than community voices being heard, it is both the hearing and the listening to what is important to our whole community."

The Alliance is working in partnership with the Department of Human Services and the National Indigenous Australians Agency (NIAA) to deliver a 12-month action plan focused on community priorities.

Together, they are focused on closing the gap for First Nations people in the area across a range of justice, education and youth targets.

South Australian Human Services Minister, Nat Cook, said the government is committed to helping Port Augusta and Davenport find and implement solutions which improve safety and connections to one another.

"This isn't just about reducing harm, it's about investing in hope, culture and connection," Ms Cook said.

"It's the strength, truth, and leadership of Aboriginal and local communities that have shaped this work.

"Their voices are the backbone of a plan that's not just about delivering programs, it's about transforming lives."
