The first British colonies on Tasmania appeared circa 1803. Small numbers of whalers and sealers set up communities along the Northern Coast and the Bass Strait islands. The whalers and sealers began to trade with the Aboriginal Tasmanians along the North Coast. Most of the goods traded were seal skins, dogs and Aboriginal women. Sporadic skirmishes over land and women occurred between the settlers and the Aboriginal people, but few records of the conflict exist. In late 1803 to early 1804 colonisation of Tasmania began to formalise. The governor of New South Wales built military outposts along the River Derwent in southern Tasmania, and also on the Tamar River in the north to prevent French interests in the area. These outposts began to grow into small communities as new settlers and convicts came from Great Britain. Communities around Hobart and Launceston were established, which would eventually become the largest settlements on Tasmania, and railways connecting the towns were built. The early colonies on Tasmania constantly suffered from lack of food.
By 1820, British authorities controlled around 15 percent of Tasmania, stretching from Hobart to Launceston. Much of this land had been settled for farming, with colonists exporting grain to Britain and rearing cattle for local consumption. It was during this agricultural expansion that the population of colonists grew from 7,185 in 1821 to 24,279 in 1830. During this time, the British authorities ceded rural land owned by the Crown to British colonists. About 6,000 settlers received land along rivers on the Eastern Midland Plain between Hobart and Launceston under this scheme, and many colonists also settled along the Meander River west of Launceston. These settlers reared sheep and exported wool and mutton to Northern England. The total number of sheep reared on Tasmania was around 1,000,000. Over time, the British acquired over 30 percent of Tasmanian land, and the entire area became known as the Settled Districts. By 1823 the population of Aboriginal people was estimated at around 2,000. Dogs were first introduced to Tasmania by British colonists, used to hunt game, such as kangaroos. Aboriginal people, convicts and settlers used the dogs as a way to source food and also used dog fur for clothing and shoes. They also used the kangaroo meat and fur that was hunted by the dogs as produce to sell. This hunting culture slowed down the agricultural development.
Impact on the native population
Authors such as Jeremy Paxman and Niall Ferguson have concluded that the British colonisation of Tasmania led to the genocide of the Aboriginal Tasmanians. Although distantly related, the people on the island had been separate from the peoples of the mainland for around 8,000 years. It is unknown how many Aboriginal people were living there when the Dutch arrived in 1642, nor when James Cook landed in 1777, but when the British began their colonisation in 1803, there were an estimated 7,000-8,000, many of whom were already dying from diseases thought to have been contracted from European sailors, explorers and seal hunters. In addition, many had been left infertile by venereal disease. The introduction of technologically advanced, brutal convicts and less than sympathetic settlers must have contributed to their misery. Almost all of the 7,000 Indigenous Tasmanians were killed during a period of colonisation lasting around 27 years. By the end of Britain's colonisation in 1830, at least two families of Aboriginal people were living on the Island. By 1835 only one Aboriginal family remained on the island, who were living in a white sealing village near the Bass Strait, hiding from British authorities. Recent figures for the number of people claiming Aboriginal Tasmanian descent vary according to the criteria used to determine this identity, ranging from 6,000 to over 23,000.
