Sydney is a great place to spend a weekend away. The City has plenty of night life and action. Darling Harbour is a quick Walk from town hall station which provides an easy way to go out and leave the car at home. Parking for a car in the city is surprisingly expensive so public transport is a good option. The trains stop running earlier than the buses, you can catch these from outside the QVB building and tend to run to around 3am, after this time a taxi is the only option. There are many places you can go out to that do not have a cover charge to get in.
During the day a great trip is to catch a ferry from Circular Quay to Watsons Bay. These are many food places to a grab a bite to eat there as well as a nice walk to look at The Gap and out to the sea. The ferry goes back along a nice path with views of the city and the ability to get off at Double Bay for a wander around, it is quite scenic there and there are many boutique stores dotted around the place. Sydney has a lot to offer in a small area, a weekend there would be a nice getaway.
