Mount Tilga, a hill located near in the Central West region of New South Wales, Australia, was said to be the exact centre of New South Wales. However, establishing the centre of an irregular shape is not a straightforward matter. Just where the centre of the State lies is open to dispute. According to Geoscience Australia a possible centre for New South Wales is just off Cockies Road, 33 km west-north-west of Tottenham, a small town 110 km west of Dubbo. This spot, (-32.16333°N, 147.01667°W) south of the Fiveways Intersection, is marked by a cairn constructed for Australia's Bicentennial celebrations in 1988. Mount Tilga is 307 m above sea level and it rises sharply out of the plain, approximately 8 km north of Condobolin.
