All tour editions had white discs. Only original PolyGram issues were not.

Here are all Aussie Versions:

Aussie U.S. Version PolyGram here - https://www.discogs.com/Shania-Twai...release/7697154

Aussie U.S. Version Universal here - https://www.discogs.com/Shania-Twai...release/5105867

Aussie International Version Tour Edition PolyGram with slip Box here - https://www.discogs.com/Shania-Twai.../release/908646

Aussie International Version Tour Edition PolyGram (and later Universal) without Slipcover here - https://www.discogs.com/Shania-Twai...release/7729292

Aussie Special Edition Australian Exclusive Version here Universal - https://www.discogs.com/Shania-Twai.../release/574652

And of course the 'Australian Exclusive' version with signature most likely release through Universal but not sure as I've never seen it.

Lots of Aussie issues.
