A New Zealander who killed a teenager in Brisbane with a single punch has been sentenced to seven years in prison.
Armstrong Renata, 23, was today sentenced at the Brisbane Supreme Court for unlawful striking causing the death of 18-year-old Cole Miller in January last year.
The offence carries a maximum penalty of life in jail.
Renata was with friends when he approached Mr Miller in the early hours of a Sunday morning in the Fortitude Valley nightclub district.
Fellow New Zealander Daniel Maxwell, is said to have asked "do you want to see something funny?", before challenging Mr Miller to a fight.
Renata then struck Mr Miller on the head, causing him to fall to the ground.
The teenager, a promising water polo player, suffered massive brain trauma, and his life support was turned off the next day.
Mr Miller's father today wept as he read emotional victim impact statements in court, saying the crime had turned his family into turmoil, and that the nightmare would never end for their family.
He also read a statement from Cole's mother, who said she will never be at peace, and wishes for death so she can be reunited with her son.
Renata's lawyer told the court the Kiwi moved to Australia in 2008, and has a five-year-old son who lives with his mother.
Renata also read a tearful letter of apology to the court, saying he would give anything to be able to turn back time.
In summing up Justice Helen Bowskill noted Renata's criminal history, which includes assault occasioning bodily harm.
He must serve at least 80 per cent of the seven-year term.
Renata's friend Daniel Maxwell was previously convicted of common assault and affray over the incident, and was handed an 18-month suspended sentence.
He was deported to New Zealand in August.
