In 1910 Moloney won the Victorian seat of Indi for Labor. He lost it in 1913, but regained it in 1914. In the same year, on 15 April, he was married to Margaret Mary Mills. However, it was his opposition to conscription which lost him the seat for good in 1917. He relocated to New South Wales and in 1919 became the first Labor representative for Hume. Despite representing a New South Wales seat, he continued to live in Melbourne, but built up a strong support base in Hume. He was one of only a small number of people who have represented more than one state or territory in the Parliament. In 1928, Moloney fell gravely ill with appendicitis, and was operated on by his parliamentary colleague Earle Page. Moloney was Minister for Markets and Transport from 1929 to 1931 as part of the Scullin government. He negotiated Australia's first trade treaty with Canada, and was rewarded with a parliamentary ovation. Despite many continuing exploits, including preparing for the Imperial Economic Conference of 1932, to be held at Ottawa, Canada, Moloney lost his seat in the conservative landslide of 1931.
Later life
There were no parliamentary pensions, which left Moloney almost destitute. He sold his house and moved in with his sister-in-law. With former colleague Richard Keane, he managed to buy two old mining dumps near Bendigo, which were sold to Collins House for ₤3000. He also became active in the share market. By 1939 he was president of the Australian Labor Party in Victoria, but, despite two unsuccessful Senate campaigns, he withdrew from politics in 1943, when Labor won office. Although he gradually moved away from the ALP, he certainly never joined the DLP and in fact, disagreed with many of the policies of the Democratic Labor Party. Chairman of the Victorian Dried Fruits Board from 1936–1957, he was only able to retire after Prime MinisterRobert Menzies ensured he would be provided with a pension. He was closely associated with Archbishop Daniel Mannix, and was always interested in horse-racing. Moloney died on 8 May 1961 and was given a state funeral. He was remembered by Archbishop Guilford Young as "outstanding among a great generation of Catholic men who had a special Catholic ethos".
