The State Office Block was a landmark modernist skyscraper complex on a block bounded by Phillip, Bent and Macquarie streets in the Sydney central business district. Completed in 1965 and designed in the modernist International style by Ken Woolley from the NSW Government Architect's Office, the 128-metre-high building (known colloquially as the "Black Stump") took the title of the tallest building in Australia from the nearby AMP Building until 1967, the 170 metre Australia Square tower was completed. Designed to hold offices of the NSW Government, including the cabinet and the Premier's office, the State Office Block was demolished in 1997 to make way Aurora Place.
