Well I think I have nutted this one out with the help of PhilMH's Platterlog uploads at 45spaces.
So here goes nothing.

If there are no issues with the above, I will add a date of 1991.
That Australian chart entry date is a year to the week after this album entered the US charts, so I don't know why it look so long to catch on here; I'm not sure that Australian release was in 1987, but it was before August 1988, as it is listed in the first Platterlog that I have, showing distribution by WEA. It was probably a European pressing, and could have been either the one with barcode (a different barcode to this issue) or without. Greg's images show distributed by BMG Arista Ariola Australia on the disc (BMG acquired worldwide distribution for MCA and other labels in 1992, I think), but Universal Music Australia on the back insert, so that looks like a transitional issue from about 1998/1999, when MCA took over PolyGram and morphed into Universal Music Group.
My copy of this is identical to "gregs45s" which i purchased January, 2001. A look through the Australian Ebay listings show "Disctronics B" pressings with the same Cat#, Barcode, artwork, tracks etc... which would give a date pre December, 1995. Entered the Australian charts 18/09/1988.
