In Australia, the northernmost border of South Australia, and the southernmost border of the Northern Territory are defined by 26° south.
Additionally, 26° south also defines an approximately 127 metre section of the Western Australia/Northern Territory border at Surveyor Generals Corner due to inaccuracies in the 1920s for fixing positions under constraints of available technology.[1]
The parallel also defines part of the Queensland and South Australia border between the 138th and 141st meridians east.
