Surveyor Generals Corner

Surveyor Generals Corner is a boundary point in the desert region where Western Australia, South Australia, and Northern Territory meet. Two concrete pillars stand approximately 127 meters apart, marking the exact junction where these three territories intersect.

The monument was established in 1968 when surveyor Barry Allwright conducted the initial survey of the boundary point and erected monuments there. This marker documented the official border definition between the three Australian territories.

The Irrunytju Aboriginal Community controls access to this boundary marker and requires visitors to obtain specific permits to enter their traditional lands. The location holds importance for local communities as a reference point within their ancestral territory.

Reaching this remote location requires multiple permits, including approval from the Irrunytju Community Office and a transit permit for the Great Central Road. Traveling through the desert requires preparation and careful planning before departure.

Three different time zones converge at this location, offering visitors the unusual opportunity to experience New Year three times on the same day. This temporal phenomenon makes this boundary point a memorable and distinctive destination.
