escorted by police vehicles from state and federal authorities. After office Politicians, including prime ministers, are usually granted certain privileges after leaving office, such as office accommodation, staff assistance, and a Life Gold Pass which entitles the holder to travel within Australia for "non-commercial" purposes at government expense. In 2017, then prime minister Malcolm Turnbull said the pass should be available only to former prime ministers, though he would not use it when he was no longer PM. Only one prime minister who had left the Federal Parliament ever returned. Stanley Bruce was defeated in his own seat in 1929 while prime minister but was re-elected to parliament in 1931. Other prime ministers were elected to parliaments other than the Australian federal parliament: Sir George Reid was elected to the UK House of Commons (after his term as High Commissioner to the UK), and Frank Forde was re-elected to the Queensland Parliament (after his term as High Commissioner to Canada, and a failed attempt to re-enter the Federal Parliament). Acting prime ministers and succession The deputy prime minister becomes acting prime minister if the prime minister is unable to undertake the role for a short time, for example if they are ill, overseas or on leave (and if both are unavailable, then another senior minister takes on this role). The Acts Interpretation Act 1901 confers upon acting ministers "the same power and authority with respect to the absent Minister's statutory responsibilities". If the prime minister were to die, then the deputy prime minister would be appointed prime minister by the governor-general until the government votes for another member to be its leader. This happened when Harold Holt disappeared in 1967, when John McEwen was appointed prime minister. On the other two occasions that the prime minister has died in office, in 1939 and 1945, Earle Page and Frank Forde, respectively, were appointed prime minister. In the early 20th century, overseas travel generally required long journeys by ship. As a result, some held the position of acting prime minister for significant periods of time, including William Watt (16 months, 1918–1919), George Pearce (7 months, 1916), Alfred Deakin (6 months, 1902), Joseph Cook (5 months, 1921), James Fenton (19 weeks, 1930–1931), John Forrest (4 months, 1907), and Arthur Fadden (4 months, 1941). Fadden was acting prime minister for a cumulative total of 676 days (over 22 months) between 1941 and 1958. Honours
