welcome Unraveler......fear not with the stinkers too much unless you live north of Exmouth on the West or North Queensland on the east where the nice and friendly Box Jelly Fish likes to hang out. As a general rule jellies come into shore due to warmer waters and persistent onshore winds....so after a few days of an onshore like a NE over here on the east you will see lots of blue bottles hanging out waiting to annoy you. If you want to avoid them get yourself a costume / stocking and cover yrself head to toe or if you are really concerned just stay out of the water. Bluies shouldn't kill ya - just make you un-comfortable for a few mins....the upside being that if they are keeping everyone out of the waves then you can cover up and get yourself some uncrowded ones

If they do annoy ya wash off in warm water and rub on some antihistamine or anaesthetic ointment. Coke-cola and vinegar have also been touted as good solutions. Lots of people suggest that urine can have a nice soothing effect - not sure if I agree with this one but its probably best to try this one when its your mates who get stung not yourself
