"In the state that you were in you should not have been in the nightclub at all," he told Johnston.
"Other patrons should not have been at risk of your simmering antagonism."
Judge Staude said the victim could not see the attack coming and could do nothing to protect himself.
"This was an offence aggravated by the fact that it was entirely unprovoked," he said.
Tristan Ceccato after he suffered injuries to his head, face, teeth and jaw.
Mr Ceccato described the assault and its aftermath as a nightmare and the worst experience of his life, the court heard.
