I have the following set of points (there are far more). Originally they were given to me without any decimals. I was able to correctly plot them into arcmap however they don't line up with my other shapes, they float off to no where. I've tried re projecting and define projection, but they still go no where. I can only conclude they are incorrect co-ordinates, as when I try to google maps a point (-33.726298, 127.575079) google maps can't find it.
Points in the area I am looking at should look like -37.837266, 145.040987. I cannot understand how I was able to create shapes from these points that look correct, but don't line up with my layers, other than the distance between each point is still correct. They are meant to be in GDA94, but I still can't locate them in the Melbourne area where they should be.
