Here's a photo of one of the markers that're at the corner of the Northern Territory, South Australia and Western Australia.
There's actually two markers, the first one was in the wrong place by about ten metres ... a bit of a stuff up ... so they did their maths right and put another one in the right spot ... and then they put this one (in the picture) there ... which has a plaque on it, but there's a slight mistake that I noticed on the plaque
... can you see where the problem lies?
Here's another photo of my placing my bottom on the Surveyor General's Corner plaque and doing a wee fart to let him know that I don't think much of his work and that he shouldn't have been given the position of Surveyor General to the Queen, her Majesty, if he can't work out that W.A. should be on the large side of the plaque, not N.T. ... though perhaps some smart-arse Territorian with an oxy-welder came along to have a picnic one day and assert the right of the outback's lonely picnic area policy of tomfoolery.
