Yes! Sydney has a host of public transport which is reliable, clean, and so easy to use.  The Opal Card is a great way to easily buy tickets, and can be used on all public transport, making switching modes really easy.  Buses are a great way to get around the CBD as well as getting out to the suburbs. Ferries run from Circular Quay to Manly Beach, Taronga Zoo, Watsons Bay and other key tourist locations. The trains and light rail are also really easy to use, with colour coded maps to ensure you are (literally) on the right track. The CBD loop is also a great way to easily get from Central, to Circular Quay, and more, If you love being on two wheels, you'll be happy to know that Sydney is a really cycle-friendly city! You'll find plenty of bike rental locations too.
