Sydney is supported by highly developed, modern infrastructure.
* **Water and Sewer:** Managed primarily by Sydney Water. The city’s main water supply comes from a network of dams, most notably the massive Warragamba Dam, supplemented by the Sydney Desalination Plant during periods of drought. * **Electricity:** The grid is operated by providers like Ausgrid and Endeavor Energy, transitioning increasingly toward renewable inputs (solar and wind) supported by the state grid. * **Telecommunications:** Sydney enjoys comprehensive cellular coverage (4G/5G) via major telcos like Telstra, Optus, and TPG. Broadband internet is provided through the federally owned National Broadband Network (NBN), offering high-speed fiber connections across the metropolis.
