Just alerting folks in this forum to this thread, in case you don't frequent the United Airlines Mileage Plus forum:

The dinner will be during the week of July 20 - the exact date isn't given. Some of the posts are about questions to ask and/or things to suggest. Those (and what goes on at the dinner, which could be posted after it takes place) may be relevant even to people who don't fly UA much, as what UA does could have broader implications for the future of Australia-US travel.
