I think you're quite right Jon. I've been enjoying the TV documentary series 'Bondi Rescue', which follows the activities of the lifeguards on Bondi beach.
Apart from grabbing drowning folk in the deadly 'rips' or currents, they seem to spend quite some time dealing with bluey stings (venomous jellyfish), yanking highly poisonous sea snakes out of the water (enough venom in one bite to kill dozens of people) even removing a deadly spider from a holiday maker's rucksack.
Add to that sounding the shark siren and resuscitating collapsed people who have dangerous heatstroke and dehydration, one is left puzzled as to why anyone in their right mind would even set foot on blooming Bondi beach! There seems to be a continuous procession of 'ambos' on blue lights making their way there.
