In 1881, it was reported to have a population of 995; while this remained static for some decades, by 1936, it was reported to have a population of over 1,500, with 361 dwellings and 106 businesses, with the surrounding area described as "one of the best agricultural districts in this state". In the 1950s, the council offices were based out of the former Jamestown Institute, by then converted to a memorial hall. In 1979, the council launched a program of kerbing and sealing Jamestown streets. On 1 January 1991, it merged into the surrounding District Council of Jamestown; the merged council would itself amalgamate with surrounding municipalities to form the Northern Areas Council in 1997.[1][2][3]
