Officers from adult prisons armed with capsicum spray and batons will be handed control of security at Victoria's youth justice centres following a mass breakout and riots.
About 40 staff from Corrections Victoria will maintain order in the Malmsbury and Parkville centres and newly created Grevillea unit in Barwon prison.
The measure follows the escape of 15 inmates on Wednesday, who stole numerous cars and assaulted people during a 24-hour crime spree while on the run.
The last of the group were caught on Thursday afternoon and will be transferred to the Grevillea unit.
The corrections staff will be issued with capsicum spray and batons and assume the security roles that previously fell to youth justice workers, who were only allowed shields for self protection.
Premier Daniel Andrews says the new officers will deliver order.
"We're dealing with a cohort of violent offenders - conduct that the youth justice system was never built to deal with," he told reporters on Friday.
The centres will still be managed by the Department of Health and Human Services but the new corrections staff will manage security and teach youth justice workers tactics on dealing with rioting youths.
Corrections Commissioner Jan Shuard said she is confident the new staff will be able to take control of a future riot.
"They are able to take swift and certain action where they need to assure the safety and security of the centre," she said.
The government has promised to build a youth prison to handle violent prisoners but there are no details yet on its capacity or location.
Numerous riots have been staged at Malmsbury and Parkville over the past 18 months, with inmates climbing roofs and assaulting guards.
The opposition called for Youth Affairs Minister Jenny Mikakos to resign but Mr Andrews stood by her on Friday.
Victoria Police will maintain order at the centres until the corrections officers start work on Monday.
Anglican Bishop Philip Huggins said the system for dealing with young people was too fragmented and intervention was coming too late.
Seven offenders have been charged with escaping a youth justice centre, intentionally causing injury, vehicle theft, aggravated burglary and other offences.
They appeared before a magistrate on Friday and were remanded to appear at a children's court at a later date.
