About Baulkham Hills

Baulkham Hills is an established suburb in Sydney's Hills District, about 28 kilometres north-west of the CBD. Most of it sits in The Hills Shire, with a small section south of the M2 Hills Motorway in the City of Parramatta. The 2021 Census counted 37,415 residents, little changed from 37,050 in 2016. The median age is 39, households average 3 people, and the median household income is $2,474 a week, with detached family houses the usual home and large Australian, English, Chinese and Indian ancestry groups.

Windsor Road, Old Northern Road and Seven Hills Road meet at Baulkham Hills Junction, and the M2 is the main drive toward the city. There is no metro station inside the suburb, so Hills Showground and Norwest on the Metro North West and Bankstown Line, a little over 2 kilometres away, and Castle Hill station beside Castle Towers are the nearest rail options. CDC NSW express buses, including route 610X, run via the M2 to the Queen Victoria Building, and route 601 links Parramatta and Rouse Hill. Selective Baulkham Hills High School on Windsor Road, together with Crestwood High School and Model Farms High School, is a large part of why families choose the suburb for its schools and space.

Baulkham Hills falls under postcode 2153 and is governed by the The Hills Shire Council (Local Government Area). For federal elections, residents vote in the electorate of Mitchell, while state elections fall under the Castle Hill electorate.
