A Canberra prisoner 75 days into a hunger strike that has seen him hospitalised for weeks has been granted parole.

Isa Islam, 45, has been in prison since a frenzied stabbing on a Canberra man at Ainslie Shops in 2009.

The victim was left quadriplegic, and requires an electric wheelchair for movement.

Islam has refused substantial food since December 9, claiming prison staff had refused to let him pray.

His sentence was extended in 2015 after he attacked a fellow prisoner and his new non-parole period expired in January 2019.

A spokeswoman for the ACT's Justice and Community Safety Directorate said Islam had not said he wished to begin eating in light of the decision.

"The ACT Government is aware the Sentence Administration Board has today granted conditional parole to a detainee who has been engaged in a recent period of voluntary starvation," she said.

"The detainee has not yet indicated whether he intends to commence refeeding."

The spokeswoman said parole decisions were made independently of government.

"The ACT has a robust parole system which prioritises the safety of the community," she said.

"The ACT Government is unable to provide specific comment on matters relating to an individual detainee due to privacy considerations."
