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 kilometres (21 mi) west-north-west of Tottenham, a small town 110 kilometres (68 mi) west of Dubbo. This spot, (32°09′48″S 147°01′00″E) south of the Fiveways Intersection, is marked by a cairn constructed for Australia's Bicentennial celebrations in 1988.
Mount Tilga is 307 metres (1,007 ft) above sea level and it rises sharply out of the plain, approximately 8 kilometres (5.0 mi) north of Condobolin.
