I just had a quick look and I’m not sure if the dates for 2009 have been released. The 2008 main event finished on Jan 20th. So I’m guessing around the 16th will be the date.
I have also started up this thread http://www.pokeraffiliateprograms.com/forums/general-poker-affiliate-discussion/15918-pap-cap-event-australian-2009-a.html#post92895 to get a better idea of numbers and to spark interest.
January is also the time for the Australian Open tennis in Melbourne and is mid-summer. Great time for a holiday and to hit the beach. Melbourne is also the cafe and party capital of Australia.
