Port Hacking effectively forms the southern boundary of Sydney's suburban sprawl. Working inland from the sea, the indented north bank of Port Hacking is formed by the suburbs of Cronulla, Woolooware, Burraneer, Caringbah South, Dolans Bay, Port Hacking, Lilli Pilli, Yowie Bay, Miranda, Gymea Bay and Grays Point. The southern bank is largely undeveloped land within the Royal National Park, although the small communities of Bundeena and Maianbar are found there. Warumbul and Gundamaian are other localities on the southern bank, in the Royal National Park. Cronulla and National Park Ferry Cruises operates a regular passenger ferry service that crosses Port Hacking, connecting Cronulla and its railway station to Bundeena. They also operate cruises along Port Hacking that depart from Cronulla.
