The red and yellow flag is used in many countries (New Zealand for one, and
I'm pretty sure Australia is another). In New Zealand, the usual situation is
that when lifeguards are in attendance the beachside building they use as
their office/HQ flies the flag of that particular club (usually a logo, and
often sponsored). Two red and yellow flags will be placed on temporary poles
hammered into the sand of the beach at either end of the patrolled area, and
the public are advised to "Swim between the flags".
