One of Australia's remotest Aboriginal communities remained tense yesterday after police reinforcements were flown in to quell three days of rioting. The extra police were rushed to Kalumburu, an impoverished community at the end of a dirt track in the hot and barren Kimberley region of northwest Australia. The violence began on Sunday night with an argument between two teenage boys from rival tribal groups. It swiftly escalated, with opposing families fighting each other with iron bars and rocks. At least three people, including two children, were hurt after being hit by rocks. A 12-year-old girl had her front teeth knocked out. Four police officers were flown in from the nearby towns of Wyndham and Kununurra on Wednesday to reinforce the settlement's two resident police. Community leaders said high unemployment, appalling living conditions and a sense of despair were the underlying reasons for the violence in the town, which lies 3,000km north of the state capital, Perth. 'This is a community which has been very neglected for generations by all levels of government,' said Leonie Cameron, the chief executive officer of the Kalumburu Aboriginal Corporation. 'There is a pressure cooker environment which means that small incidents can cause a major eruption. We have houses which accommodate more than 20 people. They are not getting enough sleep, or enough food.' Like many remote Aboriginal settlements, Kalumburu was originally a church-run mission in which rival tribes were corralled together. Its 500 people come from three clans, the Balanggarra, the Kwini and the Waanambal. Two-thirds of the community is under the age of 16. 'Young people feel an overwhelming sense of despair and lack of hope,' Ms Cameron said. 'There are no jobs, no sporting facilities ... we need massive intervention from the government.'
