Strong Tomorrow is an initiative of Save the Children's Aboriginal Services.
It provides intensive mentoring to young people aged 10 to 14 who are prolific offenders in the south-east metropolitan district.
Aboriginal services co-ordinator Karina Chicote said the project aimed to reduce youth crime by 40 per cent, but it had exceeded expectations, with most participants reducing their criminal activity by at least 85 per cent.

READ NOWSchool attendance has also increased for most participants by at least 60 per cent.
"The program has achieved this through providing mentoring, advocacy, practical support and working in collaboration with other services," she said.
"The young people have built a strong, supportive relationship with their mentor and consequently reported they feel more capable of making good decisions, respond better to challenging situations and have become more connected to their community."
Ms Chicote said Save the Children was excited to again be a finalist in the Constable Care Child Safety Awards, after winning the community award for its One Step Closer program in 2014.
"We believe that programs like Strong Tomorrow are critical to supporting arguably some of the most vulnerable young people in our community and we're committed to working with the community to give these young people a fair start to life."
Winners will be announced at an ceremony on August 1 at the Perth Convention and Exhibition Centre.
