The complex consists of a mix of commercial, professional and health-care services provided to the population of Sydney's Hills District.

The park grew with the expanding population of the area, and the first business to be constructed was the Baulkham Hills Coles supermarket, known as Norwest Markettown.

In 1993, Cathay Pacific paid $5.2M for land in Norwest business park to establish a $260 million international data centre.

Other large-scale corporations in the Norwest Business Park include Vertiv, ResMed, AAMI Insurance, Fitness First gym, and one of the Reserve Bank of Australia's data centres.

[2] Transport to the business park is possible by car, metro, bus or by cycling on the off-road Windsor Road or M7 cycleways.

In late March 2007, the North West T-Way opened, providing relief to the traffic congested business park.

The T-Way provides frequent bus services between Parramatta and Rouse Hill, promoting the use of public transport in and around Sydney.

CDC NSW route T64 between Parramatta and Rouse Hill travels through the business park seven days a week.
