Long Description:
In 1988 the Royal Geographical Society of Australasia determined, as a Bicentennial project, the geographical centre of Australia. A monument was erected to mark the location and named in honour of Dr. Bruce P Lambert, a former Director of the Division of National Mapping, for his achievements in the national survey, levelling and mapping of the continent. Similar to the centre of gravity method, the location was calculated from 24,500 points at the high water mark of Australia's coastline.

In the 1930s when Dr C.T. Madigan travelled through Central Australia he calculated the centre of gravity by using a metal cut-out of Australia with a plumb bob and string. His crude measurement was surprisingly accurate as he selected a point less than 11 kilometres due west of this present position.

The computed result of the 1988 project was:

25 degrees 36 minutes 36.4 seconds south latitude, 134 degrees 21 minutes 17.3 seconds east longitude; position on SG53-06 Finke 1:250,000 and 5746 Beddome 1:100,000 scale maps.
