The 24th ANU Open is taking place in Canberra on the weekend of the 30th and 31st of July. The venue is the ANU School of Art, Childers Street, Acton, a 10 minute walk from Canberra City. First prize in the Open is $1000 with a $400 first prize in the Under 1600 event.
Entries for the event can be made online at http://vesus.org/festivals/2016-anu-chess-festival/ Entry fees are $70 for adults, $50 for juniors and concessions if you register before 22nd July. (NB Only registration is required to avoid the late fee, and you can still pay on the day)
If you are from interstate and thinking of playing, University House (the venue for the O2C Doeberl Cup) is a good choice for accommodation, while there are plenty of other places to stay within walking distance of the venue.
The ANU Open is part of the 2016 ANU Chess Festival which has a number of other chess activities (team blitz, schools teams tournament) from the 29th of July to the 3rd of August.
