Gordon moved to Adelaide and worked as a grain merchant. He became a deacon of the Congregational Church, and met Anna Louise Peel, a pianist at his local church, whom he married on 4 April 1888. Later that year he joined the South Australian Register, with whom he was employed for about 20 years, initially in their Port Adelaide office, then progressed through the ranks as commercial and financial editor and chief of the reporting staff, and agricultural editor of The Observer, and contributed leading articles to both papers. He was in the Press gallery of the Legislative Council and the House of Assembly for 17 years, and for 10 years was chief of the Hansard staff. As "Timoleon", he contributed the "City Scratchings" column in The Kapunda Herald from 1901 to 1909. He was invited to accompany Clement Giles on his expedition to central Australia, riding on horseback. On his return journey he interviewed Lord Kintore, who was returning from Port Darwin, at Charlotte Waters, and accompanied him to Adelaide. Returning from the trek, Gordon became an enthusiastic supporter of the development of central Australia, writing numerous books and articles on the subject over the next twenty years, including The Central State and The 'Nile' of Australia. Additionally, Gordon edited several editions of the annual Handbook of South Australia. Gordon regularly advocated for the improvement of the farming and pastoral industries in South Australia, as well as transportation throughout the state. His level of influence was such that he was able to persuade the government to establish a freezing works at Port Adelaide. Involved in Liberal politics, Gordon unsuccessfully stood as a Commonwealth Liberal PartySenate candidate at the 1910 election before his election as a member of the House of Representatives at the 1911 Boothby by-election following the death of Labor incumbent Lee Batchelor. In parliament Gordon was a vocal supporter of the development of South and central Australia and was a member of the Royal Commission on the fruit industry. Gordon lost his seat at the 1913 election but switched to state politics and was elected to the SouthAustralian Legislative Council in 1913. Gordon was appointed Minister for Education and Repatriation by Premier Archibald Peake in July 1917 but resigned the next month in protest at the Commonwealth Liberal Party's coalition with the Nationalist Party of Australia, and rejected further offers of ministerial posts from Peake. Gordon became party leader in the council in 1918 and President of the South Australian Legislative Council from 1932 until his retirement from politics in 1944. He was made a knight bachelor in 1925 and in 1927 chaired the Australian delegation to the International Economic Conference, Geneva. He served variously as President of the Australian Liberal Union, the Associated Chambers of Commerce of Australia, the Adelaide Chamber of Commerce, and President of the South Australian branch of Toc H and the Sailors' and Soldiers' Fathers' Association. He was also a director of numerous companies. Referred to as "a highly principled man with a strong personality", Gordon died at his home in Victoria Avenue, Unley Park, South Australia, survived by two sons and two daughters. One son, Douglas Peel Gordon, served in the Legislative Council while the second, John, was a pilot who was awarded the Military Cross in World War I.
