It does look like a scam. Notice the eBay pictures are all cropped from the ones on the Aussie site such that the "bikesales.com.au" stamps do not show up. In the cases where the Aussie photo is not cropped, the stamp is relatively easy to rub off. And, see the evidence of the rub-outs on the left arm of the rear stand in the photo with the license plate. It's interesting to see the two sets of photos side-by-side and compare.
It's also a shame that people try to scam others and rip them off. And, it's too bad that dirtbags that do this often are not chased down and a not usually punished for their attempted (or committed) frauds.
