This is my opinion and not meant to be 'dividing'.
The Island has a Dingo population, native animal population.
A few years ago they did do a Cull when these sorts of attacks became regular, I think it halved the population, after which things settled down.
6-8 pups per year, lots of Dogs on the ground, natural food sources are scarce, guess where they are looking for food as a "pack mentality hunter" ??
I would not be at all surprised if an Adult was taken down and killed, they attacked a mother and child on a beach recently too.
As bad as some may take this, it is time to seek out and cull the dogs that hang around the human population or are human social,
half or reduce the dogs to 1/3 of the current population.
Kill off ANY aggressive animal and pack leaders approaching humans.
BUT try to keep the native strain/lineage alive, let them breed back to numbers, cull for control not to extinction.
While culling seems like a terrible solution, it does work, and they will bounce back.
My family.... I would try to be prepared in this environment, I would definitely defend my children and take the life of the animal if I could,
but they are smart and fast, when acting as a pack you may not even get the opportunity to inflict injury.
It will happen in seconds, and then its over.
Protected or not, you will never get into trouble defending a human life against an animal attack.
