Centre points of Australia

Along this line of longitude (which runs from near Ceduna in South Australia to the base of the Coburg Peninsula in Northern Territory) he judged the halfway point to be the centre of the continent.

He calculated the centre of gravity by using a metal cut-out of Australia with a plumb bob and string, and selected a point less than 11 kilometres due west of the present position.

Further information on datum types and their applications is available from the geodesy pages, or from the Inter-governmental Committee on Surveying & Mapping (ICSM).

Australia's centre of population in June 2016 was approximately 35 kilometres (22 mi) east of the town of Ivanhoe in western New South Wales.

However, the Government body responsible for determining such matters, Geoscience Australia, has adopted the following locations as the official centroid for each of the States:[14] The Geographic Centre of the Australian Capital Territory is at the former site of the Honeysuckle Creek Tracking Station.

(35° 29' 24" South, 149° 00' 05" East) The Geographic Centre of the Northern Territory is approximately 91 km west-north-west of Tennant Creek.
