You can definitely walk all around Sydney…the city part. You can also take buses to the beaches. But if your hotel is centrally located, you can walk to the bridge, opera house, gardens, shopping, etc. My friend and I were there for 3 days and only walked. It would have been cool to take a bus to the beaches tho. And you can take ferry rides across the harbour for pretty cheap. Sydney is AMAZING!!!! Darling Harbour is super fun, they have a mall, an awesome bowling alley, imax theater, festivals, bars, clubs, gardens, soooo much!

You can definitely find a lot of stuff to do in Sydney! Have a great time!!!
