A culturally-led Aboriginal-staffed service for families who have contact with the justice and child protection system has been recognised for its work in south-west Sydney.

The 'Helping Families Overcome Entrenchment Through Aboriginal Ways' project delivered through the Family Advisor Unit (FAU) - an arm of the NSW state government's Department of Communities and Justice - was designed by yamagigu South West Sydney DCJ staff and One Mob One Job team.

It's been recognised with Australian Good Design Awards gold in the Public Sector Services category.

"This award is a powerful validation of DCJ's commitment to Aboriginal self-determination and leadership in service reform," DCJ Executive Director of Transforming Aboriginal Outcomes Bianca Jarrett said.

"This isn't just an award; it's proof that when we empower Aboriginal people to design the solutions for their own communities, we achieve incredible results.

"The Family Advisor Unit is transforming lives by putting culture and community at the heart of our work. We are immensely proud of the team for this well-deserved recognition."

The project, as a direct point of contact for families engaged with justice and child protection systems, is staffed by senior Aboriginal practitioners.

NSW's DCJ acknowledges minimal improvements in the overrepresentation of Indigenous children out-of-home care and no progress in overrepresentation of Indigenous adults in custody and children in detention per National Agreement on Closing the Gap targets.

'Helping Families Overcome Entrenchment Through Aboriginal Ways' works with families and caseworks to formulate plans with holistic and family-centred measures as means of support.

DCJ secretary Michael Tidball congratulated the Family Advisor Unit on their work, the award and commitment to 'culturally safe approaches' said to improve outcomes for Aboriginal families and children.

"It has set a benchmark for service delivery across the sector," Mr Tidball said.

"Thank you for your immense contributions."
