Thanks for responding so quickly and clearing that up!
It looks like the Australian version may actually contain Portuguese, at least according to this site:

For some reason a lot of Australian discs include Portuguese. That same site is where I finally found a version of Disney's Cinderella with Portuguese. Now to try to find out if the Australian version is actually locked to Region B...
UPDATE: I searched the eBay Australia site, and was able to find an image of the back cover showing Portuguese audio and subtitles. I cleaned up the low-rez picture as best I could and uploaded it to the database, and then I updated the language info. I still don't have confirmation on the region, but since it's a Warner release, I believe there's a good chance it should be region-free.
