Rubbish Herb. The further north you go the more nasties in the water.

And not just Irukandji, they are a relatively recent phenomenon .... how about their larger cousin the Box Jelly or Stinger?

That's what keeps people out of the water ...... & they can come up out of the water on to the beach for a snack.
But also the tourists themselves ruin these destinations by continual stubborn/lazy actions & ignorance in dumping their fish frames & waste into the waters not far from where they are staying.
It not only attracts crocs but large sharks(bull) as well.
The same thing happens around & near the creek & boat ramp where I go fishing every year north of Rockhampton.
The local council provide a fish dump on land away from any water ways where the frames & waste can be picked over by crows & hawks.

Off-shore drum-line netting is the only answer to the crocs and shark problem, unless you can fly a trio of drones where they can spot any predators heading for the shore.
I'm ALSO experimenting with the idea that a colourless dye can be sprayed over the swimming beach waters which when comes into contact with these jellyfish beasties turns them a bright red or yellow for identification from drones.
