Saw this on facebook and thought i'd share. Doesn't say what species however a few people hospitalised. Could just be bluebottles?

We do get a few blue bottles there at this time of year & it's always the swimming area i see them due to the current/bank.

Yeah only see occasional one though, most ive seen is maybe 5 in same day, makes you do a little jig to avoid getting stung. Seems the bank collects them then pushes them down towards beach (plus the current sweeps that way around the point wall). Dunno if it is right but ive found it helps if you're out on water if they get you grab a handful of sand to get them off asap.

Poor fella, if you get or see anyone with anything like the photo of the boys sting with the lines on it get them to go to hospital, I slept 2 days straight like it was an hour after stung on arm by box jellyfish very similar sting just bigger.
