You can get the standard version (and 3rd party options) for cheaper, but I think this is a pretty good price for a Limited Edition Switch Pro Controller.
Ships from and Sold by Amazon Japan, so it should be 100% legit.
Mod Edit 12/7 10pm: Price has increased from $80.63 to $81.20
It seems that the ones coming from Amazon Japan are sold by third party sellers but shipped by Amazon
You can tell by going on amazon.co.jp and copy-pasting the exact amazon.com.au listing name (including the Japanese)
