Cameron Corner Survey Marker

Cameron Corner Survey Marker is a concrete pillar marking the precise point where Queensland, New South Wales and South Australia meet. The structure stands at this tristate border junction, replacing an earlier wooden post from the 1880s.

Surveyor John Brewer Cameron established this border marker during the first official survey of Queensland's western boundary between eighteen seventy-nine and eighteen eighty-one. The precise placement of this boundary point was essential to distinguish the three territories clearly.

The marker represents early colonial cooperation between Australian territories and reflects the importance of precise border demarcation for customs and trade.

The location sits in an arid region far from major towns, so visitors should bring water, fuel and gear suitable for extreme conditions. Access requires a robust vehicle and planning for extended travel times across remote outback terrain.

The site experiences three separate New Year celebrations as different time zones meet at this precise location. This unusual feature makes it a distinctive place to witness how time boundaries actually work on the ground.
