For his role on Homicide, co-producer Dorothy Crawford provided George with money to buy a hat for his character to wear. Not wanting to wear a hat for the role, George purchased the silliest hat he could find, hoping that the show's limited budget wouldn't permit a replacement, thus allowing him to go without. Unfortunately, the hat he purchased was approved by Crawford and he had to wear it throughout his time on the show.
George died of complications of a stroke on the 12th of July, 2004, on the Goldcoast, in Queensland, Australia.

George: (On the toughness of his character in Homicide in comparison to himself) The real George Mallaby is a coward. He hates fighting. He just talks fast - very fast.
George: [On scriptwriting] Writing requires a mood. It might be called a creative mood, I suppose. Unfortunately for those close to me, the mood often seems to come around 4am. I get a spasm of creativity and just have to jump out of bed and start writing.
George: [On founding one of Australia's first hazelnut farms] [It's] basic protection against the insecurity of show business.
