My contemporaries were more upset about the Nobel than I was not to be recognised. One of them labelled it the 'No-Bell' prize! But it was fine by me. There's no Nobel Prize in astronomy and I was really proud that it was my stars that had convinced the prize committee that there was good physics in astrophysics.

Working at the hospital, I found that my surgical skills were not as good as I expected. One time it took me two hours to do a surgical operation which could have been completed in 30 minutes by other surgeons. My supervisors were very tough on new residents like me, and I lost confidence in my ability.

People not believing me. It's getting a little easier, but it's funny how people will say, "I don't think you can do that." Then you do it, and they say "That was great" and you say, "Well, I've got this other idea." "Naw, I don't think you can do that." So you do it again. When I said I was going to find the Titanic , no one believed it. When I said I was going to find the Bismarck , everyone believed it, and then I failed in my first attempt to find the Bismarck . So people expect you to succeed, but they don't want to stick their own necks out, and so risk-taking can be very lonely at times. You know that classic saying, which is very true: "Failure is an orphan, but success has many fathers." I'll tell you, when I'm most at risk, I look around, and there are not a whole lot of people there. But as soon as I succeed, they say, "We were always there." And I say, "Yeah, but 500 miles behind me."

So we had to take this special exam and I flunked it. Erv Upton passed it, and I was scared. I figured if I failed it, I wouldn’t have any chance of getting in. So I failed it beautifully. ... And so it was the first year of this general college, which gave an Associate of Arts degree after two years, and that was expected to be a terminal course. It turned out it wasn’t.

The two things that I miss most when living out of Australia are the bush and the Pacific coast, especially fishing in the surf at night! My father had a workshop and I learned to be a carpenter, a skill that has resulted in the manufacture of some very substantial coffee tables and a fair amount of time working on houses.

On returning to Brisbane, I realised fairly quickly that I am an experimentalist at heart. A career as a diagnostic virologist was not for me!

I share Alfred Nobel's conviction that war is the greatest of all human disasters. Infectious disease runs a good second.
