Tony Eggleton, AO, CVO (30 April 1932 − 20 May 2023) was an Australian political consultant who was the Federal Director of the Liberal Party of Australia.
He first came to public prominence as the press secretary to the Prime Minister of Australia, Harold Holt, at the time of the latter's disappearance and presumed drowning in December 1967.
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.
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).
Eggleton became a public figure, frequently appearing on television, as he dealt with the intense domestic and international media interest in the search for Holt and subsequent events.
Eggleton was retained as press secretary by Holt's successor, John Gorton, and in 1970 he played a leading role in organising the tour of Australia by Queen Elizabeth II.
In this capacity he was the party's Campaign Director at seven federal elections (1975, 1977, 1980, 1983, 1984, 1987 and 1990), under three different leaders (Fraser, Andrew Peacock and John Howard).
