Andrea Byrne started her journalism and media career as a local radio reporter for Guildford-based County Sound Radio. She then joined local television station MyTV Portsmouth as a reporter, but when the station was forced to lay off staff, she was promoted to news editor at the station. When Portsmouth TV ceased broadcasting she moved to Oxford’s local TV station, Six TV before joining Thames Valley Tonight on ITV Thames Valley as a reporter. It was while here that she produced a series of special reports on the Royal Air Force, reporting on pilots and their training at RAF Odiham before they were posted to Afghanistan, which was also shown nationally on ITV2 and placed runner-up in the regional Royal Television Society awards.
Following the departure of Lucy Owen to BBC Wales’ flagship news programme Wales Today in November 2007, Byrne applied for the resulting vacancy on ITV News Cymru Wales. On 17 December, it was announced that she had beaten 80 other applicants to the post, and undertook her first show opposite Jonathan Hill on 14 January 2008. Prior to her debut, Benfield moved from Surrey to Cardiff Bay.
Since joining ITV Wales, Byrne has presented a number of various regional non-news programmes for the station, including the arts and entertainment series The Wales Show, documentary series Tidal Wales, ITV Wales weekly political programme Sharp End and coverage of the Royal Welsh Show and the National Eisteddfod.
Byrne is also a relief newscaster for ITV News weekend bulletins, debuting in June 2010. She has also appeared as a relief presenter for the network’s Lunchtime News, Evening News and News at Ten, as well as for GMTV and Daybreak.
