About Castle Hill

Castle Hill is the prestigious heart of The Hills District, an established Sydney suburb where leafy streets and quality homes reflect its affluent character. With a population over 40,000 and a median income well above Sydney averages, it's evolved from semi-rural beginnings into a sophisticated urban village. The Metro Northwest line has transformed connectivity, putting the CBD within easy reach while preserving the suburb's distinct identity.

Life here centres on Castle Towers, one of Sydney's premier shopping destinations, surrounded by excellent schools both public and private. The suburb is decidedly family-oriented—parks are plentiful, streets are safe, and community ties are strong. Castle Hill attracts established families and professionals who value quality living, excellent schools, and suburban tranquility within reach of the city. The Hills heritage is celebrated at Castle Hill Showground, home to the famous annual show.

Castle Hill falls under postcode 2154 and is governed by The Hills Shire Council (LGA). For state elections, residents vote in the Castle Hill electorate.
