The city, growing outward from Sydney Harbor to the Blue Mountains, has a compact core but a sprawling metropolitan area covering 700 square miles (1,120 km² ). It is served by a public transport system of trains, buses, ferries, light rail lines and a generally well-planned roadway system. Its international airport, the world's oldest commercial international airport, is about 5 miles (8 km) south of the city center. Most tourist attractions - except for surfing beaches - are around the harbor or the central business district. Visitors can easily see the sights by walking, using the Hop-On Hop-Off tourist bus or taking a harbor cruise or a City Circle train.
The car rental market is well developed with the major international brands represented. Your valid driver's license from home will be honored. Just remember that like the Brits, the Aussies drive on the left side of the road. Drinking while driving laws are strict and enforced with random breathalyzer stops.
The city encourages two-wheel transportation through an expanding cycling network, courses, challenges and an annual October festival. So far the network has eight miles (12.5 km) separated cycleways and 37 miles (60 km) of shared paths. Bikes may be rented at various shops.
Sydney has a vast train and light-rail network in the city with links to the suburbs and the region. Central Station is the main terminus. Trains for popular Bondi Beach leave from Matin Place Station. Circular Quay is a hub for rail and the ferries serving spots around the harbor. Most trains stop running between midnight and 4:30 am, replaced by NightRide buses operating on 13 routes. The airport line from City Circle stations runs from 5 am to midnight daily.
The State Transit Authority (STA) operates Sydney Buses, which provides local and suburban service, including Route 400 with airport stops. A free shuttle loops through the Central Business District. Between 7 am and 7 pm, only the pre-paid tickets or the Opal smart card are accepted on buses. Route hours are posted at most stops with a few operating 24 hours. Hail the bus to get on; push STOP button to get off. Private bus companies offer longer haul service from Eddy Avenue outside Central Station.
Metered taxis may be hailed on the street, hired at designated taxi stands or booked directly with one of the city's private taxi companies. Ridesharing services include Uber and Australian versions like GoCatch and Shebah just for women with female drivers.
