Katherine Nguyen, a friend of one of the accused, Fostar Akoteu, had earlier told the court Akoteu was wearing a black puffy jacket and sunglasses on his head. She said that she did not see who punched Mr Aguiar last but that she clearly saw Akoteu stomping on his head after the alleged victim fell.

Pub bouncer Raymond Thompson, who tried to break up the fight, said one Polynesian man threw the last punch after which Mr Thompson pushed the alleged attacker against the wall. Mr Thompson said that while he was holding him, another Polynesian man stomped on the victim's head as he lay on the ground.

He said the bigger of the two men was wearing a brown T-shirt, dark jeans and black hoodie-type jacket but could not remember whether this was the man who allegedly threw the last punch. He said only two Islander men were involved in the fight.

Andrew Edmunds, a pub patron, had earlier told the court one man had delivered the last punch, a "dog shot, in the back of the head, didn't see it coming", while another man, whom he identified as the "main aggressor", stomped on the victim as he lay on the ground, possibly on his chest.

Several other witnesses said they did not have a clear view of the fight or they could not identify people who may have punched the victim but that there were three alleged attackers. Akoteu, 22, Jacob Palutele, 22 and Sioeli Seau, 19, are charged with Mr Aguiar's murder.
