When you're out and about this summer, it's easy to forget the need to keep yourself protected from the sun. So listen out for the new Sun Sound!

More practical than training seagulls to drop hats on people, the Sun Sound is a catchy harmony played at regular intervals on loud speakers at beaches, reminding you to be sun safe.

This radical musical experiment, produced by acclaimed musician Ben Lee, is being trialed at Gosford and Cronulla beaches this summer.

If you hear it, remember to protect your skin with a hat, sunglasses, sunscreen, shirt and some shade. So listen out for it and keep yourself safe in the sun.
