Combine two great Sydney experiences into one with a hop-on hop off Sydney Harbour cruise and a hop-on hop-off city bus tour. With your 24-hour passes -- one for each tour -- explore Sydney and Bondi aboard an open-top double-decker bus and visit sites such as the Sydney Opera House, The Rocks, Chinatown and the Royal Botanic Gardens. On your Sydney Harbour cruise, stop at sites such as Darling Harbour, Circular Quay, Watsons Bay and Luna Park. This is the perfect way to experience the best of Sydney!
