I would go to a Barnes and Noble or your local book store (just noticed you're in Australia) and look at the magazine rack, or even where you saw the magazine. They usually have a big variety and that magazine might be there. Atleast you could look at the titles of the magazines and then google each one of them to see if it was a back issue. I would think the magazines would have a link for past issues, with covers. That's what I would do atleast if I found it that important.
