Hi acrusa & Welcome to Flyertalk:
Hotel specific questions are best addressed in Country Specific Travel Forum under Travel & Dining, or, as in this case, the Hotel Programs Forum. Check out the Hyatt Gold Passport thread here: http://www.flyertalk.com/forum/hyatt...2011-a-28.html

According to Francophlies' Post #419 (close to last post), PH Sydney is scheduled to reopen Nov 2011 & estimated to begin accepting reservations in Q311.
