Anthony "Tony" Eggleton, AO, CVO (born 30 April 1932), is a former Federal Director of the Liberal Party of Australia. He is best remembered by many Australians as the press secretary to the Prime Minister of Australia, Harold Holt, at the time of the latter's disappearance and death in December 1967.
Eggleton was born in the United Kingdom and educated at King Alfred's College in Wantage, Berkshire. He was a cub reporter on his hometown paper in Swindon, Wiltshire, when in 1950 he was invited to undertake work experience with the Bendigo Advertiser in Australia. He later joined the Australian Broadcasting Commission and played a role with the introduction of television in Australia in 1956. In 1960 he became director of public relations for the Royal Australian Navy. In 1963 he was the Foundation President of the National Press Club in Canberra.
In his position with the Navy, he handled the media and public affairs issues arising from Australia's worst peacetime naval disaster in 1964 (the sinking of HMAS Voyager, with the loss of 82 lives). This brought him to the attention of the Prime Minister, Sir Robert Menzies, who hired him as his press secretary in 1965. When Menzies retired in January 1966, his successor Harold Holt kept Eggleton on.
