@philwill.I think all the scans here are UK/European,and it could be that your Disc scan is a duplication of the one already on,difficult to tell,as it's a bit faded on one side,but it looks the same,perhaps it could serve as a replacement (Mods)?.I would imagine that this one was entered as Australian because the stock European release was put on sale there as well?,if so,then it should be made "International".
Just added CD image from my European release, which seems indistinguishable in all aspects from this Australian release (cat#s, barcode and artwork), so should it be International?
Only difference is in release date, which Music Master 14th Ed. (1993) gives as April '90.
