Scott Charles McLeod pleaded guilty to one charge of assault occasioning bodily harm when he appeared via video link from Hakea Prison on November 18.
The prosecutor said that on February 5, Mcleod was sitting in the day room area at a table when the victim came over, accusing him of stealing his freezer bags.
An argument ensued, which resulted in McLeod throwing a flask of boiling hot water at the victim. Both wrestled, with the victim slipping on the water on the floor and breaking his ankle. He received scalding on his face and body from the boiling water.
