Champ was serving with the
63rd Regiment of Foot as an ensign by 1826 and was posted with them to Sydney,
New South Wales in October 1828. Some of the regiment was detached as a garrison force for the
Macquarie Harbour Penal Station,
Van Diemens Land (now
Tasmania) in 1829, and Champ was amongst them. As a lieutenant with the 63rd, he participated in the
Black War campaign which was an attempt to segregate
Tasmanian Aborigines near the end of 1830. The 63rd left New South Wales and Van Diemens Land in 1834 to deploy to
India and
Burma and Champ left with the regiment. However, he had apparently enjoyed his time in Australia and later in 1834 he resigned his army commission and returned to Van Diemens Land to enter the civil service. Champ then became an assistant police magistrate, before being appointed as the commandant of
Port Arthur penitentiary (succeeding
Charles O'Hara Booth) in 1844. ==Political career==
