Isn't using the phrase "cultural appropriation" without being American a cultural appropriation? This idea and terminology was originally invented and developed in the US, so being Australian, please stop culturally appropriating our cultural appropriation. However, if you still feel you have the right to use it publicly, then you've started to understand why the Koala Kare exists. The creators of the brand felt the same way as you.
