He said Nicholson bound the victim's legs and threatened to kill him and his children. The man's wallet and a computer tablet were stolen and Nicholson told him not to call police or he would come back and kill him. The victim managed to free himself and ring police from a neighbour's house.
Nicholson initially denied any involvement but later said he went to the victim's home to scare him as he had been spreading rumours in the community.
Judge McDonald said the court must recognise the fact Nicholson was prepared to give evidence against the alleged co-offender, who has yet to enter pleas.
Earlier, Crown prosecutor Nicole Dore submitted a starting point of between seven and nine years in jail, because the attack was serious and premeditated, although unsophisticated.
The fact Nicholson and the alleged co-offender were arrested a couple of hours after the home invasion did not undermine the seriousness of the offence, she said.
Nicholson's lawyer, Arthur Fairley, said his client fell into a bad lifestyle and was truly sorry for his actions. He said there was no question Nicholson let down himself and his parents, who were in court. Mr Fairley said Nicholson was a young man, co-operated with police and had a supportive family.
Judge McDonald sentenced him to four years and four months in jail.
