Sydney has an extensive and continuously evolving transportation network.
* **Public Transit:** Transport for NSW oversees a vast system. **Sydney Trains** provides extensive heavy commuter rail across the suburbs. **Sydney Metro** is a rapidly expanding, driverless rapid transit system. A massive fleet of buses and the iconic **Sydney Ferries** (operating out of Circular Quay) complete the network. The CBD and inner east are also served by a light rail (tram) network. * **Roads and Highways:** A complex network of motorways (including the M4, M5, M7, and M2) connects the sprawling suburbs, many of which are electronic toll roads. * **Airports:** Sydney Kingsford Smith Airport (SYD) is Australia’s busiest international and domestic gateway. A second major airport, Western Sydney International (Nancy-Bird Walton) Airport, is under construction and due to open in 2026. * **Active Transport:** While historically car-dependent, Sydney is heavily investing in dedicated bicycle infrastructure and walking paths, particularly in the inner city and along coastal routes. * **Emerging:** EV charging networks are expanding rapidly across municipal parking and commercial centers.
