I'm inclined to agree, but clearly someone important thinks the comfest shouldn't be on at the same time as another major event, or they wouldn't have delayed it for the commonwealth games.
I was wrong,
the article was in the Australian, not the Age. It says that the festival people also think the swimming won't be a problem, but the very fact that they have to argue that indicates that someone else doesn't necessarily agree with them.
Meanwhile, visitvictoria.com.au is listing comfest as starting March 28th, 2007, but whether that's subject to change or not is debatable.
