In 1892, he presided over the commission appointed by the New South Wales Government to inquire into the military condition of that colony.[1] He was appointed a Knight Commander of the Order of the Bath in the 1902 Coronation Honours list published on 26 June 1902,[4][5] and invested as such by King Edward VII at Buckingham Palace on 24 October 1902.[6] Due to economic conditions in the 1890s, Tulloch chose to resign as commandant to make way for a less costly commandant.[3] He left Melbourne in 1894.[3]
