South Australian borders
Today South Australia's land borders are defined to the west by the 129° east longitude (129° east) with Western Australia, to the north by the 26th parallel south latitude (26° south) with the Northern Territory and Queensland and to the east by 141° east longitude (141° east) with Queensland, New South Wales and Victoria; however this is not where all borders are actually marked on the ground.
The South Australian boundaries are shared with the West Australian border, the Northern Territory border, the Queensland borders. the New South Wales border and the Victorian border That is all States and Territories except for the Australian Capital Territory and Tasmania.

From 1825 to 1829 129° east was the NSW border.
Following the settlement of the Swan River Colony (SRC) in 1829 (2 May 1829 - Map), the eastern boundary was declared to be 129° east, that is coinciding with the western boundary of New South Wales at the time.
From 1829 to 1832 129° east was the SRC/NSW border.
From 1832 to 1846 129° east was the WA/NSW border.
South Australia became a colony in 1836 and until 1846 would be surrounded on land by New South Wales (NSW), with South Australia extending west to the 132° east longitude. (132° east) and north to 26° south (28 December 1836 - Map).
From 1836 to 1846 129° east was the WA/NSW border. 132° east was the SA/NSW border as were 26° south and 141° east.
From 1846 to 1847 129° east was the WA/NSW border and the WA/NA border. 132° east was the SA/NSW border, while 26° south became the SA/NA border and 141° east remained the SA/NSW border.
In 1847 the colony of North Australia was revoked and reincorporated into New South Wales. (15 April 1847 - Map), so South Australia was once again surrounded by New South Wales on all land borders.
From 1847 to 1860 129° east was once again the WA/NSW border.
From 1847 132° east was again the SA/NSW border, and 26° south was also the SA/NSW border. 141° east would remain the SA/NSW border until 1851.
From 1851 141° east would change to include both the SA/NSW border and the SA/VIC border.
From 1859 141° east would change to include the SA/QLD border, the SA/NSW border and the SA/VIC border.
From this time on South Australia's western border was also the West Australian border.
From 1860 129° east became the SA/WA border from south of 26° south & the WA/NSW border north of 26° south.
From 1862 26° south became shared as the SA/NSW border and the SA/QLD border between 139° east and 141° east.
In 1863 that part of New South Wales to the north of South Australia was annexed to South Australia by Letters Patent as the Northern Territory of South Australia, which was shortened to the Northern Territory (6 July 1863 - Map).
From 1863 to 1911 129° east was the WA/NToSA border north of 26° south & the WA/SA border south of 26° south. 26° south became the SA/NToSA border.
From 1911 to 1927 129° east was the WA/NT border north of 26° south & the WA/SA border to the south. 26° south became the SA/NT border.
From 1927 26° south became the SA/CA border.
From 1931 26° south once again became the SA/NT border.

The Border Corners

Surveyor Generals Corner
The actual West Australian border with the Northern Territory and South Australia, which has been marked on the ground, is not as straight as it looks, with the WA/NT and WA/SA borders being displaced by approximately 127m due to early survey errors within the limits of technology available in the 1920s.
The 127 metre section that runs east-west along the 26° south is part of the border between Western Australia and the Northern Territory. In June 1968, two monuments were erected to mark each end of this 127 metre sideways section, the easternmost of these monuments, being where all three borders meet, was named Surveyor Generals Corner. 
Cameron Corner is the point in the outback of eastern Australia where the boundary lines of the states of Queensland, South Australia, and New South Wales meet.
Haddon Corner is the north-eastern corner of the state of South Australia, where it meets with the border of Queensland. The point is located in the outback Channel Country district.
Poeppel Corner (known as Poeppels Corner in Queensland) at latitude 26° S and longitude 138° E is a corner of state boundaries in Australia, where the state of Queensland meets South Australia and the Northern Territory.
