Northmead depot began operation in 1932 under the name of Parramatta Bus Service. This was when steam trams from Rogans Hill to Westmead ceased operation. Alf & Flow McIntosh were the owners of this service.

The depot was situated on Briens Road Northmead and was later relocated to the corner of Church St & Dunlop St.

Bosnjaks Bus Service Purchased the company in 1963 and the depot was operated from Church St.

It was then relocated to the present location in Boundary Rd, Northmead in September 1978.

Northmead Depot has a staff of approximately 190.
