Great experience. After purchasing, you can get the iVenture card in certain kiosks. We came to the one at Darling Harbour. With the card, you can pick a large selection of attractions, activities and tours. The Wildlife Sydney and Sea Life are located nearby and we went there. Wildlife is a great indoor zoo where you can meet Koala and Kangaroo. The Sea Life has penguins. Price at Traveloka is cheaper than on the spot purchase.
