A prisoner has been locked in his cell for 23 hours a day since a fire damaged security and communications systems at a Victorian jail, a court has been told.
And 20-year-old Adhel Adhel, who was jailed on Friday for trying to break into a house, could remain in lockdown at Port Phillip prison into 2018.
Defence lawyer Martin Kozlowski told the Victorian County Court that Adhel had been in 23-hour lockdown for the past nine days and had little fresh air.
An electrical fault sparked a fire that ripped through a control room and put security cameras and internal communications out of action on November 29.
The prison has been on a "restricted regime" since, with staff managing the amount of time inmates are spending out of their cells.
Some of the inmates have been restricted to an hour outside their cells while others are getting two hours.
This is compared to the usual 11 hours per day, and staff are only taking small groups outside at a time.
The Department of Justice would not confirm when these restrictions would end but it's understood they will remain throughout Christmas.
Adhel was jailed for 10 months after he and five others attempted to break into a St Albans home wielding sticks, bricks and stakes.
The group kicked and hit the windows and front door, terrorising the occupants before running away.
