Not the most violent by any means but still interesting:

Battle of Manners Street (3rd April 1943) https://en.wikipedia.org/wiki/Battle_of_Manners_Street
During the Second Word War American soldiers stationed in Wellington New Zealand were causing friction with the local soldiers. Their higher-ups were giving the yankees cigarettes and silk stockings (very rare in NZ because of restriction for the war effort), and they were as a result stealing a lot of the girls of men who were overseas serving.
Naturally the kiwis were miffed, but things came to a head when the Americans started trying to stop maori soldiers from entering dance halls and clubs - the kiwis (maori and pakeha alike) were pissed. A stand off escalates into violence when the Americans take off their belts and start beating at their opposition.
A massive brawl then ensues, spills out onto the man street and is joined by a thousand men. End result is dozens of injuries and rumoured to be two deaths of American servicemen.
The reason I say 'rumoured' is because the whole thing was covered up by the government and command morale reasons - even today a lot of kiwis have no idea about it. I know that similar clashes between Americans and the people they were allied with happened in Aussie too.
