Norwest is a suburb of Sydney located in the north-western part of the metropolitan area. It is bordered by Bella Vista and Rouse Hill to the east, Cherrybrook and Pennant Hills to the south, and The Ponds and Kellyville Ridge to the west.
Norwest is approximately 30 kilometres from the Sydney central business district. The majority of dwellings are detached houses on relatively large blocks of land; however, there has been an increase in apartments in recent years.
Norwest contains a commercial core known as Norwest Business Park which is home to many corporate headquarters, including those of Foxtel, Microsoft Australia, Lion Nathan and Boral Limited.
