One Ton Post, Mungindi Queensland

It's a marker of sheer determination - in the thick of the bush outside Mungindi, the One Ton Post stands out as a remarkable physical monument erected by surveyor JB Cameron to mark the end of the arduous three-year task of surveying the straight section of the Queensland/New South Wales border, from Cameron Corner to the Barwon River.

Following the completion of the survey from Barringun to Cameron Corner, JB Cameron then set out to survey the 199.5 miles east from Barringun to the Barwon River. The One Ton Post was placed on the west bank of the Barwon River near Mungindi to mark the end of the survey of the twenty-ninth parallel (degree of latitude) in October 1881. Remarkably, you can place your hands on the very peg that JB Cameron erected with his own hands over a century ago. It gets better; the One Ton Post is the original survey peg whereas at Cameron Corner, sadly they've had to replace theirs with a cement marker.
