Gus appeared with virtually every Westward/TSW presenter, including the late Ian Stirling, Fern Britton, Judi Spiers, David Fitzgerald, Ruth Langsford and Sally Meen.
The character was given the full name Augustus Jeremiah Honeybun by some continuity announcers, and was said to have been found under a gorse bush on Dartmoor in 1961 by the founders of Westward Television.
From 1987 to 1990, TSW used to often opt out of showing the first and last Children's ITV in-vision continuity links of the day so it could fit in Gus' birthday slot on weekday afternoons.
The last-ever Gus Honeybun programme aired on 31 December 1992, at the tail end of the final TSW Today, which paid tribute to the station's 11 years of service.
In the post-apocalyptic novel by Jasper Fforde entitled Shades of Grey, which is set 1500 years into the future, Devon and Cornwall are known as 'The Honeybun Peninsula'.
In 2024, Gus Honeybun's story featured in several episodes of the BBC Radio 6 Music weekend programme, Radcliffe and Maconie, in which listeners recalled their experiences of the rabbit.
