Geographical Centre of Simpson Desert - NT

The Geographical Centre of the Simpson Desert was dertermined by the "centre of gravity" method by Warren Bonython and Dennis Bartell. The first people to attempt to reach the Geo Centre of the Simpson Desert before the aid of GPS navigation were Willem Kempen, Judith Kempen and David Hodgkinson driving two Suzuki 1300's. On 4th July 1987 they reached the approximate position of the Geo Centre and erected a plaque to commemorate the event. This position though has not been reclaimed as yet.

The first successful arrival at the Centre was by the CFA 4WD Club of Victoria in 1993. In 1995, the same Club erected the Tower that now marks the Centre of The Simpson. Those people that venture to the "Geo Centre" as it is commonly known, can add their names to the Visitors Book that sits inside a Jerry Can, alongside of the Tower.
