Combine a seasonal whale-watching cruise with a Sydney Attraction Pass during your vacation. From May to November, a catamaran takes you from Sydney Harbour out on the open water in search of humpback and southern right whales migrating through the Pacific Ocean. You can also create your own sightseeing itinerary with an attractions pass that is valid for three months after the cruise. Gain admission to your choice of three attractions on a list of some 40 options that include tours of Sydney Opera House, Sydney Explorer Hop on Hop-off Bus, SEA life Sydney Aquarium and activities around Sydney.
