In February 2007, Ian revealed on Four Corners that he was a recovering alcoholic who used to drink at least three bottles of wine a night - topped up with beer and spirits. The interview is now screened to substance abuse patients in private rehab clinics.
Ian graduated from Nottingham University with a degree in politics in 1985.
Ian changed his surname from Perrygrove to Dickson during the 1980s when he began working in the music industry because he thought Dickson sounded better.
Ian met his wife, Melinda Bell, at a nightclub in Bristol in 1984. They have two daughters together. The eldest, Esma was born in 1991, followed by Edie, who was born in 1992.
Ian owns his own TV production company which is named 'Water Cooler'.
In April 2006, Dicko appeared as a judge on the Song For The Socceroos.
In 2005, Dicko hosted the morning show on both Sydney (Vega 95.3) & Melbourne (Vega 91.5) radio stations.
Ian was the General Manager of Marketing for BMG in Sydney, Australia.
In September 2006, Ian and Paulini Curuenavuli were listed as #47 in TV Week's 'Top 50 most memorable moments on Australian television' list, for the scene on Australian Idol when he made comments on Paulini's dress and her weight.
Dicko: I wouldn't mind having a pop at [Maria] Sharapova. I think she'd be a right grunter in the sack. And I'm a dud root, so I need all the help I can get.
Dicko: My fortunes changed when I moved to Australia. I had a great life back in the UK, earned a great living, had a great family and a great home life. I moved to Australia and everything got turned up to 11. About the hair, it looks 100 times better now. I saw Doug Mulray on StarStruck last night and I remember when I was playing football people used to say, "Mulray! Pass the ball, Mulray!" Just to sledge me, they used to call me Doug Mulray. Doug's a great bloke. If I had half of his wit, I'd be very happy.
Dicko: (on Dicko being a person or a character) I like to think I'm a person. Dicko wasn't a nickname or a character that I made up to go onto the show. What Idol did was show me how much one person with a voice and a network can resonate with the public. I guess it's hard not to play with that or even recognise it, but for me it's an acceptance of a personal failing if I start saying that Dicko's a character. I have to deal with what I said on the show, how people relate to it and if I try to deal with it as this third party, then we get into a really weird space.
Dicko: I'll be 100 per cent honest with you. My biggest challenge is alcohol. I'm drinking way too much. I've realised why famous people check themselves in and out of rehab all the time. Because if you're in the public eye with everyone staring, the only way I've found to dampen the fear is to down three drinks really quickly.
Dicko: (on his comments to Paulini Curuenavuli on Australian Idol making the Top 50 most memorable moments on Australian television) I'm sure a lot of people thought it, and I thought I was being diplomatic! But everyone knows you probably shouldn't say that to a young lady. I'm really honoured it made the list, but the big question is: have I learnt my lesson? Probably not.
