Most train lines operate from 4:30 a.m. to midnight with certain services running overnight. Sydney's public buses are a fairly reliable form of transportation and convenient way to get to just about everywhere in the city, even its outskirts.

Sydney has an excellent and highly integrated public transport system that is widely considered the best in Australia as of 2026. The network, managed by Transport for NSW, seamlessly connects trains, buses, light rail, and the iconic Sydney Ferries through the Opal card system (or by simply tapping your credit card). The recent completion of the Sydney Metro City & Southwest line has been a game-changer, providing high-frequency, driverless trains that cut travel times across the harbor significantly. The ferries remain the "crown jewel" of the system, offering a world-class commute from Circular Quay to Manly or Watsons Bay for the price of a standard transit fare. While the system is generally punctual and clean, the primary complaint from locals remains the high cost of fares compared to other global cities and the occasional "trackwork" delays on weekends. For a tourist, Sydney's transport is exceptionally user-friendly; the "trip planner" apps are accurate, and you can reach almost every major attraction—from Bondi Beach to the Blue Mountains—without ever needing to rent a car or call an expensive ride-share.
