Sydney Opera House + Taronga Zoo + Sydney Harbour Bridge + Sydney Royal Botanic Gardens + St. Mary's Cathedral one-day tour

It is recommended that tourists apply for Sydney's local Opal card in advance to use for buses and subways, otherwise it will waste everyone's time if you apply for it temporarily (local buses/subways do not accept banknotes and coins). If tourists choose to taxi, it is also OK, but the itinerary does not include the taxi, and tourists need to pay for the taxi fare themselves
