Kotara /ˌkəˈtɑːrə/ is a suburb of Newcastle, New South Wales, Australia, located 9 kilometres (6 mi) from Newcastle's central business district. It is part of the City of Newcastle local government area.
The Australasia Coal Company operated a mine near Kotara, in the valley below the present-day northern entrance to Tickhole Tunnel. A private railway connected the screens with the Government line near the present-day triangle junctions north of Broadmeadow. Surveying for the line commenced in 1875 and the line was completed in April 1877. However, only a total of 9,052 tons was ever produced and the company went into liquidation in June 1879.
