A Hobart remand centre inmate who set fire to his cell in protest at his water being turned off during renovations will have to serve five months at Risdon.
Aiden Michael James Spaulding has pleaded guilty to a count of unlawfully setting fire to property while he was in custody in July last year.
The resulting sprinkler activation flooded an entire floor, doing more than $9,000 damage.
"It is accepted that regardless of his grievances, real or perceived, his response was not acceptable," said Acting Justice David Porter in sentencing.
"He says his motivation was to attract attention to his plight, but does not seek to excuse his behaviour."
The Supreme Court also noted the now-23-year-old's lengthy record while handing down the sentence.
