I get where you’re coming from, but killing a wild animal for being a wild animal can’t be the right approach.
K’gari has HEAPS of information about dingos. On top of that, if you get in ear shot of a ranger, they’ll talk to you about the dangers and how it’s always the tourists fault.
K’gari is a special place where dingos are still wild. Enjoying it simply involves respecting that wild animals are present and some precautions need to be taken. Otherwise, surely families can choose from heaps of other destinations that are safer.
