If you are planning to spend a few extra days in and around Sydney, there are many tourist activities available, such as ferry trips, harbour cruises (such as Captain Cook Cruises (02) 9206-1111), bus trips (Murrays 132-251), the zoo and the opera house.
There are many nearby restaurants, in Newtown (on King Street), Glebe (on Glebe Point Road) or in the city (in chinatown, for example).
