To me the fact the characters don't follow the folds, but rather appear to float over them is a much bigger indictement. (In fact they, both typed and printed characaters, seem to float over the entire backgroun, it's especially obvious if one reverses the colors in the image.
Notice that Bomford does not say something like, "It even has the same numbers for the place, book and page, the information was recorded." As that is the central item that indicates that one of the documents is a forgery.
Yes, it's interesting how the characters seem to float, and certainly the characters should follow the folds.
However, all of the obvious metadata bits in the Bomford file point toward a scanner at low resolution:

What I find out odd here is that this seems to point to an A4 size document, but I don't think that Australia's government was using A4 paper back in 1964.
