It is being held at the Centurion conference and event center on Colonade Rd in what was formerly Nepean.
(In case anyone does not have a vehicle, the bus #3 passes by Colonade Rd.)
Here are some more details about the event and info on where you can purchase tickets.
I think one of the best parts of the event is that you will be allowed to have a take home box for the chocolate desserts you do not finish!!!!
