Just in case you hadn't heard, it was renamed last year to K'gari. Not sure who decided to spell the new/older name like that, because the K is completely silent.
Holding and cuddling koalas was already illegal in most Australian states and territories, excluding Queensland
It's frustrating how vague the article is on that point. "Most excluding Queensland" could just mean "4", but I think most people would naturally assume it to mean "all apart from Queensland".
