Just putting this out there, but after smashing my shoulder several years ago, helping to carry one bloke with a smashed leg down the beach, and watching the increasing popularity of some spots, wouldn't it be a good idea to have a St John Ambulance-approved sign at each of those where people have had accidents? Suggestions; Woodman's, the Pond, Pt Walter, maybe Dutchies, Mullas and Trigg too.
The signs could listing the right number, correct location and nearest cross street. I was at Woodies last night, and for the life of me thought I'd never be able to guess where the nearest cross street was in an emergency.

Those signs in Vicco are pretty handy. In NSW it takes me about 5mim to explain to the NRMA where my car is when I have had a battery issue, so I'd hate to think how complex it would be for a serious issue at a large stretch of beach like in 13th Beach or Northern NSW.
