A New Zealand man who started the fight that killed Brisbane teenager Cole Miller has been given an 18-month suspended jail sentence.
Mr Miller and his friend Nick Pace were heading home when they crossed paths with Daniel Maxwell in Fortitude Valley's Chinatown mall on January 3, 2016.
Maxwell had been out celebrating his 21st birthday and already tried to assault several people earlier that night.
He asked his friends if they wanted to see "something funny" before challenging Mr Miller and punching the 18-year-old elite water polo player in the chest.
Mr Pace was also struck in the chest as he dodged a blow to the head.
Mr Miller was then punched from behind by Armstrong Renata, causing him to fall to the ground.
He never regained consciousness and died in hospital two days later.
Maxwell was due to stand trial in the Brisbane Supreme on Thursday for unlawful striking causing death but instead pleaded guilty to downgraded charges of assault and affray.
He was sentenced to 18 months in prison, wholly suspended, having already spent 19 months behind bars awaiting trial.
The court heard because Maxwell was in Australia on a visa he risked being deported to New Zealand as a result of his sentence.
Prosecutor David Meredith said while Maxwell could not be punished for killing Mr Miller, he was morally culpable for the "sliding doors moment" that led to the promising young man's death.
Justice Ann Lyons said what happened in the mall was appalling on every level.
