Portland is a town in New South Wales. It is 2 1/2 hours northwest of Sydney, Australia. The town of Portland is of interest as a historic mining town, and also as the place of the first cement factory in Australia, which was opened in 1902. Cement produced at the "Commonwealth Portland Cement Company" mill helped build up the cities of Sydney, Melbourne, and Canberra. "Portland cement", a phrase synonymous with high quality cement anywhere in the world, was shipped throughout Australia, until the cement mill was closed in 1991.
Portland is part of the gateway to the Central West and is located between Oberon, Mudgee, Bathurst, Lithgow, and the Blue Mountains. The town is surrounded by countryside and has many areas for bushwalking. It is close to the Wollemi National Park and the Gardens of Stone National Park.
