One of the most important signs I know, yet every year swimmers, many of them tourists,
ignore them. Where there's a sign there are members of the Australian Surf Life Savers Volunteers
who for 100 years have given their time in training,competing,& gaining certificates.
If your planning to visit our beaches simply look for the red flags & swim between them
It could save your life...& their time.

here is some history http://en.wikipedia.org/wiki/Surf_lifesaving

As well there are the Nippers...youngsters who mostly go on to become SLS's in adulthood. Please take a moment to read about this great organization
