"Skin cancer occurs when skin cells are damaged, for example, by overexposure to ultraviolet (UV) radiation from the sun."
Cancer Council Australia - Sunscreen application
Slip on some sun-protective clothing that covers as much skin as possible.
Slop on broad spectrum, water resistant SPF30 (or higher) sunscreen. Put it on 20 minutes before you go outdoors and every two hours afterwards. Sunscreen should never be used to extend the time you spend in the sun.
Slap on a hat - broad brim or legionnaire style to protect your face, head, neck and ears.
Seek shade.
Slide on some sunglasses - make sure they meet Australian Standards.
