N64 Paper Mario PAL Australia Edition

Can anyone explain to me why this is fetching so much? I’m assuming it was an Australian Only edition with a limited press run, but that’s a guess. Seller claims that only 1000 were made, but I don’t see that being realistic.

Auction Here – Price is pretty crazy.
