At the 1964 half-Senate election, Wheeldon was elected to the Australian Senate, representing the Australian Labor Party. His term commenced on 1 July 1965. He strongly opposed the Vietnam War and (though no supporter of communism) visited North Vietnam at the invitation of the North Vietnam peace committee, while Australia was involved in fighting in South Vietnam. In 1967, he spoke against the war in the United States with Jim Cairns.[2][3] According to Senator John Faulkner, Wheeldon "... showed real passion for the causes he believed in: his opposition to the Vietnam War, his support for the independence of East Timor, his abhorrence of apartheid and his deep concern about Soviet imperialism."[5]
In 1968, Wheeldon was suspected by Charles Spry, the director-general of the Australian Security Intelligence Organisation (ASIO) of having been compromised by contact Wheeldon was alleged to have had with a female member of the staff of the French embassy in Canberra, who had what appeared to be a personal relationship with Soviet diplomatic staff who were suspected of being intelligence agents.[7] In a declassified top secret "Note to Prime Minister" in 1968 (apparently prepared for the benefit of Prime Minister John Gorton), Spry characterised Wheeldon's actions as "consistent with those of at least a collaborator with the RIS [Russian Intelligence Service]. He may be a recruited agent."[8] Wheeldon was never questioned about Spry's suspicions, and the young woman who was the sole source of the accusations against him left the country and admitted herself to Horton Hospital at Surrey, a psychiatric institution.[7]
A declassified "top secret" ASIO minute from 1974 indicates that ASIO officers had "considerable doubts" at the time about the truthfulness of the young woman who claimed to be the connection between Wheeldon and the suspected Soviet agents, and that these doubts were not reflected in the file specifying the young woman's accusations against Wheeldon. The note suggests that the file Spry used to brief Prime Ministers Holt and Gorton did not reflect these doubts, either.[9]
According to Ian Hancock's biography of Gorton, in 1968 Spry sought to block Wheeldon's fiancée, Judith Werner (now Judith Wheeldon) from entering Australia on the grounds that her father was a member of the Communist Party USA, but "Gorton would have none of it. He brusquely dismissed both Spry and his file... he had no time for public servants who behaved as a law unto themselves".[10]
In 1968, Wheeldon was one of the leading critics in the Australian parliament of the Soviet Union's invasion of Czechoslovakia.[11]
During the 1970s Wheeldon worked for the United States in what a historian has called "a discreet relationship".[12]
In 1978, Wheeldon was one of the primary authors of Human Rights in the Soviet Union, a report of the Australian parliament's Joint Committee on Foreign Affairs and Defence. The report was harshly critical of the Soviet Union.[13]
In 1980, Wheeldon was a parliamentary adviser to Australia's permanent delegation to the United Nations General Assembly in New York City.[14]
After politics
In 1980, while part of Australia's delegation to the United Nations General Assembly, Wheeldon rekindled an old friendship with Rupert Murdoch, who offered him a position as Associate Editor of The Australian newspaper.[14]
Wheeldon was chief editorial writer for The Australian from 1981 to 1995. In addition, he sometimes wrote articles for the monthly magazine Quadrant and other periodicals.[14]
He died at his house in Sydney, survived by his wife, Judith (headmistress of Abbotsleigh School for Girls, 1996–2005) and their son, and a daughter and a son from his first marriage. His son with Judith is James Wheeldon, prominent Sydney barrister and former ASIC whistleblower.[2][3][15]
