Hi T-V-J, that sounds like a later repressing then, made once D.A.T.A. had set up their Australian factory, and WEA changed their name to Warner Music (circa 1991). I'm not quite sure when Australian manufacture started (also 1991, I think) but before that WEA's Australian-released CDs were the German-made ones (as was the situation for all the other companies, issuing mostly European pressings, as well as some Korean, Japanese, and occasionally US). I just checked, and two Paul Simon CDs via WEA, GRACELAND and THE RHYTHM OF THE SAINTS, were definitely German pressings on initial release (and I have an Aussie repressing of the first, in a 1995 double-pack with the African Concert VHS tape), so it is almost certain that the Aussie November 1988 release was this European release as listed in Discogs. I think you might be right about that advert, I vaguely remember it.
The Australian (11 track) issue of this (including the disc) was manufactured in Australia with the "Manufactured and Distributed by Warner Music Australia" on the back inlay. The "Digital Audio Technologies Australia" logo is on the disc.
Isn't the extra track here "Storms In Africa (Part II)" the version used for the Airline TV advertisement?
As it turns out, just Europe may be right for this one after all - it looks like this version is a reissue to add the last track, whereas the original version was issued in late 1988 under catalogue number 248375-2, and that is the version that was released in Australia on 7th November 1988 (date from Platterlog). Interestingly, the Australian version shown in Discogs has a back cover saying "Manufactured and Distributed by Warner Music Australia" (WEA didn't change its name until 1991, IIRC), yet the disc is manufactured in Germany! Working forward through the Aussie Platterlog catalogue for another couple of years, it looks like the re-released version didn't make it here.
I would say make it International - WEA centralised all their European production in Germany earlier in the decade, and chances are that this CD (as well as thousands of others from the company) were exported to WEA's sister companies in other countries for "local" release, this was certainly the case for WEA here in Australia until the early 90s, when CD factories were finally built in this country.
