The plaque contains an error, as Lambert died in 1990, not 1992. Similar to the centre-of-gravity method, the location was calculated from 24,500 points at the high-water mark of Australia's coastline. 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 (

There are two ways to judge the median centre point of
Australia. The linear centre, which is the halfway points of Australia's extreme points (Cape York, Cape Byron, South Point and Steep Point). The second is the geodetic median point, which is a more accurate method used by surveyors. It uses a

Australia to the base of the Coburg Peninsula in Northern Territory) he judged the halfway point to be the centre of the continent.

Central Australian geology in the 1930s. 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.
