I spoke in Brisbane, Australia on December 1, 2011, as part of a five-city Australian tour in late November and early December. The tour sponsor was the Q Society of Australia.

Of all the talks I gave in Australia, in Sydney, Melbourne, Perth, and Cairns, as well as in Brisbane, I think this one was the best -- although, of course, I am not seeing it from the audience's perspective. I start just before the 30 minute mark.
