[5] Keating's television career began in Northern Ireland where she presented The Video Picture Show, Channel One and the music programme Greenrock, but her big break came when she was selected to join the team of Blue Peter from 13 November 1986.

Her Blue Peter career included a trip to Moscow in 1987 during the perestroika period, swimming with sharks, abseiling down skyscrapers and standing strapped to the top of a light aircraft whilst it performed aerial acrobatics.

Keating joined BBC Radio 5 where amongst other programmes she co-hosted an early 90s afternoon show with film critic Mark Kermode titled A Game of Two Halves.

Keating was the face of Sainsbury's Reward Card from 1996 to 1997, before Edita Brychta took over towards the end of 1997, and also appeared in a TV commercial for So Good soya drink in 1999.

After undergoing conventional and alternative treatments, and spending a period away from her family on the Gold Coast, Australia, and at a hospice care in Switzerland, she died at the age of 41, on 13 April 2004, at her mother's house in Sevenoaks, Kent.
