A new purpose-built youth justice centre will be established in the Northern Territory while a pre-existing facility will be redeveloped, creating more than 400 jobs.
The NT government is working to overhaul the juvenile justice system to cut crime, stop reoffending and help young people turn their lives around.
The new $55.1 million Darwin Youth Justice Centre will create 350 local jobs with construction starting within weeks and finishing mid-2022.
The $13.1million refurbishments of the Alice Springs Youth Detention Centre will also start this month and create 69 jobs and provide new program delivery spaces, a medical and health area, advanced security as well as a new recreation field.
Both projects will create employment opportunities for 76 Indigenous people and 44 apprentices.
Families Minister Dale Wakefield said NT tradies had a pipeline of works throughout various stimulus programs and the additional projects would further boost the economy.
"Once completed, the centres will be places that give young offenders the best chance to turn their lives around and stop offending," he said.
