when you visit Sydney, the beaches to go to include Bondi beach, Coogee beach, Manly beach, all very pretty. Even in winter there are lots of people going there. Hyde Park and Botanic garden in the city is very big to walk around in. Of course the fish market is worth a visit (by light rail). If you want to eat Asian food, beside city, can go to Burwood, or Eastwood, by train.
