I found this post on a Canon (the dark side...) specific site which lists up-coming events which may be of photographic interest to some members.
There are only a few events listed at the moment, but might be worth checking periodically, you might see an event you were un-aware of.
Like the Worlds Biggest Pilates class on Manly Beach this sunday, thats my local beach so I plan to wear my fluoro lycra leotard and stand in the middle taking photos...
