Hugh Sinclair was an Australian politician. He was a member of the Australian House of Representatives from 1906 until 1919, representing the electorate of Moreton for the Anti-Socialist Party and its successors the Commonwealth Liberal Party and Nationalist Party. Sinclair was born at Cambewarra on the South Coast of New South Wales and was raised on his family's farm. He took an interest in the development of dairy co-operatives in the region and became a successful butter factory manager, at the Bengelala Dairy Company and Foley Bros. Cambewarra factories, then Foley Bros. creamery in Sydney, before becoming district manager of the Australian Dairying Company Ltd in the Manning River area for three years. In 1901, he relocated to Ipswich in Queensland as manager of the Queensland Farmers Co-operative Dairy Company, later expanding its operations across the region. He was one of the foundation members of the Ipswich Oddfellows' Lodge and was a member of the Ipswich Masonic Lodge. In 1906, he was elected to the Australian House of Representatives as the Anti-Socialist member for Moreton. After the "fusion" of 1909, Sinclair, together with the rest of the Anti-Socialists, merged with the Protectionist Party to form the Commonwealth Liberal Party, which in turn merged into the Nationalist Party in 1917. During his time in federal parliament, he was chairman of a Royal Commission into electoral laws and was the deputy chairman and then chairman of the Commonwealth Dairy Produce Pool Committee. Sinclair held Moreton until his retirement due to ill health in 1919. He reported upon standing down that he had had been very ill and that his doctors had warned him against recontesting his seat. After his retirement, he was contracted by the federal government as one of a number of butter factory representatives to visit England and make arrangements to contract with the British Government to purchase Australia's surplus butter. He later retired to Melbourne, where he died at his North Fitzroy home in 1926; he had reportedly been in "indifferent health" for some time. He was married to Mary Sinclair ; they had one son and eight daughters. His granddaughter, Heather Bonner, would go on to be an indigenous rights activist and the second wife of Neville Bonner, the first Aboriginal member of the Australian Senate.
