Surveyor General Corner markers

We went for lunch at the SGC today and for those that don't know, there. Are actually 2 posts marking the borders about 100m's apart. I'm thinking the guys must have been a bit tired when creating the plaques

I don't get it...

Unlike Hadden and Poeppels corners that have the one marker post with the plaque on top showing the borders of the relevant states, at the 'intersection' of WA, SA and NT there are 2 posts and as you can see the border markings on the plaques are completely wrong.
These are legit photos from today, surely there is another pp'er that has seen these.
The story has it that the two surveying teams, one from the south and one from the north, had their coordinates differ from each other and subsequently put in two posts. I don't know the accuracy of the story, but suffice to say, there are two posts out there But absolutely do not understand how they messed up the states borders like that

Western Australia - South Australia - Northern Territory border

A glance at most maps of Australia will tell you something that isn't quite true. The border which runs along the eastern edge of Western Australia is not actually one continuous straight line.The survey of the Western Australian border was first discussed in 1911, but it wasn't until 1922 that an agreement was signed between then Prime Minister W.M. Hughes, the 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 Surveyors General, 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 jurisdictions 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.

K&M, that would explain why we felt disorientation at the posts. The distance you drive along the main road after passing the border signs before turning north to the Site didn't make sense.... Til now

AJ, we are hoping to be here over two years, so there should be an opportunity.

Living out here we know we are lucky to travel in a part of the country that not many people get to, but to visit a spot less frequented than the South Pole? WOW! Already been there twice
