Julian married Dannii Minogue on January 1994, with the couple divorcing the following year. On December 22, 1999, Julian married actress Brooke Burns, before divorcing her in 2001.
Julian was listed as a potential nominee on the 2006 Razzie Award nominating ballot. He was suggested in the 'Worst Supporting Actor' category for his performance in the film Fantastic Four but he failed to receive a nomination.
Nip/Tuck's casting agents weren't particularly interested in having Julian audition, but he aggressively pursued the role and won the producers over with a videotaped reading he shot himself.
Julian left Australia in 1987 after he was offered a modelling job in L.A. Julian continued a modelling career throughout Europe, earning the title of 'Givenchy Man of the Year' in 1990.
Julian attended Sydney Grammar School, a private school in Australia. He then attended Sydney's University of Law. He also studied economics at the University of Wollongong in New South Wales, Australia, for a short time. He left university to become a model.
Julian has a habit of dating sexy co-workers. When he starred in Charmed he dated Shannen Doherty, and during the first season of Nip/Tuck he dated Israeli guest star, Noa Tishby.
Julian: I'd say without a doubt I've had the most sex scenes in any television show, ever. Last season I did eight sex scenes in one day - I haven't topped that yet.
Julian: I always look back on Home & Away with fondness, especially when I'm in the UK. But I had no idea what I was doing back then. I just fell into acting. It was only later that I became passionate about it.
Julian: (on accents) I use a standard American pronunciation... the difficulty comes when an actor has to think about his accent, because you can't relax and think about your role as much.
Julian: (on his Nip/Tuck character) It's the conflict inside that I really enjoy playing. My character is the lead guy, and you don't want the lead guy to be just an asshole all the time. So you have to find ways to make the audience take the journey with you.
Julian: I was pretty young when my father was prime minister, so it wasn't really a big part of my life. My folks were away a lot, meeting foreign dignitaries and that sort of thing, but it never struck me as odd. If anything it allowed me to get into all sorts of mischief.
Julian: It's very hard to step into a job when people are just dismissing you as a pretty face, and saying you got your job only because your surname is McMahon.
