As of this month, in the Riverina Youth Justice Centre alone, there were 16 people in custody - a 42 per cent reduction since January, 2020.

The state as a whole saw a drop of 26 per cent since January, with a total of 201 juveniles in custody.

The Bureau of Crime Statistics and Research's latest quarterly update also reported a drop of male juveniles in custody from 245 in December last year to 230 as of March this year.

Females also dropped by eight people, indigenous males by 10, and indigenous females by two.

A spokesperson from the Department of Communities and Justice said the figures correlated to the government's efforts on reducing youth crime.

"The NSW government's strong commitment to early intervention and diversion programs, as well as our work with young people in custody, is contributing to the reduction in custodial numbers," they said.

"This includes programs like Youth on Track delivered by Mission Australia in the Riverina, which works closely with young people in the community to reduce their risk of offending."

The Youth on Track program is an initiative by Mission Australia which helps young people follow the right path after trouble with the law.

Mission Australia's area manager for central and far west NSW, Megan Boshell, said hearing the recent figures of juveniles in custody was promising.

"Through our own evidence based assessment, we found that year to date, 100 per cent of young people in the Youth on Track program saw a reduced risk of getting into the criminal justice system," she said.

"Our program is quite unique in that it focuses on a person's criminogenic risk, and we think that has played a big part in the positive figures."

Ms Boshell explained criminogenic risk as looking into an individuals reasons to get on the wrong side of the law.

"It could be things like anti social values, substance abuse, circumstances with their family, or disengagement from education, and our program really targets those factors and looks at early intervention," she said.

During the COVID-19 pandemic and lockdown period, Ms Boshell said they maintained ways of supporting the Riverina's youth.

"We've continued to receive referrals through the pandemic in the Riverina, so there's been no significant decline, but during that time we have been supplying resources to young people to be able to stay at home and adjust to the new norm," she said.

"We also made sure services were still accessible in different models, like phone calls, video calls and thing like that which have been of huge benefit."
