From 1939 to 1946, he was Assistant Secretary to Sir Douglas Copland, who was Commonwealth Prices Commissioner and Special Economic Adviser to the Prime Minister.[4]
He joined the Department of Postwar Reconstruction 1946–49 as an economist. In 1950 he was posted to London as Official Secretary and acting Deputy High Commissioner to the United Kingdom, remaining there till 1953.
On return to Australia he joined the Department of the Treasury, where a position of Assistant Secretary was specially created for him.[3] He was First Assistant Secretary 1955-62, and Deputy Secretary 1962-66. In 1967 he was appointed to chair the Australian Universities Commission.[5]
Gorton government
In January 1968, John Gorton became Prime Minister in unusual circumstances after the drowning of Harold Holt in December 1967. Gorton did not want to continue receiving advice from the long-serving departmental secretary Sir John Bunting, and he created a new Department of the Cabinet Office for him, appointing Hewitt as Secretary of the Prime Minister's Department in March.
This appointment was not well received in the senior public service echelons in Canberra. On the plus side, Hewitt had a reputation for having a formidable mind, a grasp of detail, a capacity to make quick decisions and an impatience with red tape. On the other hand, he had always stirred strong responses in those he dealt with, and was often considered brusque and impatient.[6] But the major point in his disfavour was that he was never a part of the group of senior figures who lunched at the Commonwealth Club; they disliked him for setting himself apart from them.[7] Hewitt's appointment was also in the same anti-traditionalist mould as that of the appointment of Ainsley Gotto as Gorton's senior personal adviser. She had a number of strikes against her: she was aged only 22, she had not had the extensive experience expected of a person in such a position, and she was a woman.[8][9][10][11]
Hewitt was knighted in the 1971 New Year's Honours for his services as head of the Prime Minister's Department. Gorton left the prime ministership voluntarily in March 1971 after he barely survived a party room ballot instigated by his rival William McMahon; Gorton considered this close result to be insufficient demonstration of support for him and he called a new ballot, in which he was not a candidate.
McMahon government
McMahon succeeded Gorton as Prime Minister; one of his first acts was to restore Sir John Bunting to his old job by merging the Department of the Cabinet Office with the Prime Minister's Department, under a new name, the Department of the Prime Minister and Cabinet. Hewitt was appointed Secretary of the newly created Department of the Environment, Aborigines and the Arts. His minister was Peter Howson, who was not keen on the job (he was reported as describing it as "trees, boongs and poofters").
Whitlam government
McMahon's Liberal government survived less than two years, being soundly defeated by Gough Whitlam's Labor Party in December 1972. The new Minister for Minerals and Energy, Rex Connor, had established a good relationship with Sir Lenox Hewitt in the period leading up to the election, and he chose him to be the first Secretary of the Department of Minerals and Energy. As Graham Freudenberg wrote in A Certain Grandeur (1977):[12]
In Hewitt Connor felt he had found a kindred spirit – both were strong nationalists, both loners, both impatient of the windy orthodoxies of 'established channels'; both saw themselves as tough-minded negotiators, both authoritarian, both more easily able to inspire fear than affection, yet both had great charm in private; both were supremely confident in the ability of their applied intelligence to master any problem.
In 1974, Whitlam considered appointing Hewitt as Secretary to the Treasury, replacing Sir Frederick Wheeler, but in the end he opted to maintain the status quo. In 1974 and 1975 Hewitt was involved in dealings with Tirath Khemlani and he played a role in the Loans Affair.[13] In July 1975 he was one of a number of senior public servants summoned to give evidence to the Senate over the Loans Affair; in the event, the government claimed crown immunity from such questioning.[14]
In 1975 consideration was given to the creation of a new Department of Economic Planning, which would assume many of the functions of Treasury and reduce its influence. Hewitt was again in Whitlam's mind to head this Department, with Wheeler to be appointed Governor of the Reserve Bank. The events of 1975 culminating in the Labor government’s dismissal did not permit this plan to come to fruition.[15]
Later life
Later in 1975 Whitlam appointed Hewitt Chairman of Qantas for a five-year term.[16][17] He ended his term in 1980 amid public controversy over not being given a further five-year term by the incumbent Liberal government of Malcolm Fraser. He was offered only a one-year extension, but chose not to accept it.[18]
Hewitt turned 100 in May 2017. He celebrated his birthday with a party at the Union, University & Schools Club, which was attended by Paul Keating, Ian Sinclair, and Michael Kirby, among others.[20] He was interviewed by The Weekend Australian in January 2018 for the 50th anniversary of John Gorton becoming prime minister, and described Gorton as "a great reforming prime minister" whose "resignation was a great loss to Australian politics".[21]
Hewitt remained publicly active well into old age, having outlived many of his contemporaries. He made written submissions to parliamentary enquiries[22] and was sometimes called as a witness to share his experience. He was interviewed by Jenny Hocking in connection with her biography Gough Whitlam: His Time (2012).[23]
They had four children: Patricia, Antonia (died 1990), Hilary and Andrew. Patricia Hewitt long resided in the United Kingdom, where she became a Labour politician and government minister under Tony Blair.[31][32]
