Border corners of Australia explained

The border corners of Australia are the meeting points of state or territory borders. There are five such points, each recognised with a boundary marker, and all located in remote areas.^[1]

The five border corners are:

• Surveyor Generals CornerWA/NT/SA
• Poeppel CornerNT/SA/Qld
• Haddon CornerSA/Qld
• Cameron CornerSA/Qld/NSW
• MacCabe CornerSA/Vic/NSW

South Australia’s eastern border was supposed to follow the 141st meridian, but the first surveyors measured incorrectly.^[2] A 70 year border dispute followed, and eventually resulted in the disjointedness of MacCabe Corner, with Victoria using the original incorrect calculation, and New South Wales using the new and correct one.^[3]
