While I have never been to Fraser Island, I do know one thing. Those Dingo's have to be the skinniest, mangiest looking dingo's in Australia. Every picture you see of a Fraser Dingo, they look like there on their last legs. Is there no food for them there? Is there a Dingo population problem there?
the dingos have plenty of food to eat, they are far from starving. here's a pic of one i took in the last week when i was on the island, & he was small compared to one we had in our camp the day before.
inbetween digging up fish frames on the beach, raiding food from campsites and we even found over a dozen turtle nests they'd eaten all the eggs out of, not to mention whatever other food they eat on the island, IMHO all the dingos i saw last week were very healthy looking.
there's no population problem there, its an education problem IMHO.
I wonder what the outcome would've been if it was a Goanna or another native animal that attacked the child, Would it've been killed by rangers? or would they've asked, "Where was the parental supervision". And the parents told to be more vigilant in future.
what difference does the animal make? would the parents leave a 3yr old kid alone in croc country? probably not, but they do it where wild dogs are know to roam, does that make sense to you? because it doesn't to me.
