I do not think most people know there are two markers.
Here's a spiel on it from Geoscience Website (also including the reference to the south pole):
A glance at most maps of Australia will tell you something that isn't quite true. The border that runs along the eastern edge of Western Australia is not actually one continuous straight line.
The survey of the W.A. border was first discussed in 1911, but it wasn't until 1922 that an agreement was signed between then Prime Minister W.M. Hughes, and Acting Premier for South Australia, Mr. Bice, and the Premier of Western Australia, Sir James
Mitchell. The agreement set out the border as being a line determined by the 129th meridian east longitude. However, the agreement required that the
boundary be defined by lines running north and south from independently fixed points at
Deakin and Argyle. When survey work began on the South Australia - Northern Territory border in 1963, it was quickly realised that the earlier agreement precluded the possibility of these lines meeting exactly.
Precise survey methods confirmed this, and in June 1968, two monuments - approximately 127 metres apart - were erected at
the junction of the boundaries. This ceremony was attended by the respective Surveyor Generals, H.Comm from Western Australia, H.A. Bailey from South Australia, and P.J. Wells from the Northern Territory. The monuments common to all three territories was named Surveyor General's Corner at the suggestion of the Director of National Mapping. One interesting piece of trivia is that fewer people have visited this site than have been to the South Pole.
