Slip-Slop-Slap was the iconic and internationally recognised sun protection campaign prominent in Australia during the 1980s. Launched by Cancer Council Victoria in 1981, the Slip! Slop! Slap! campaign features a singing, dancing Sid Seagull encouraging people to reduce sun exposure and protect themselves against an increased risk of skin cancer. Sid had Australians slipping on long-sleeved clothing, slopping on sunscreen and slapping on a hat. This successful program was funded by public donations.
The health campaign was extended in later years by SunSmart to encourage the use of shade and sunglasses. That is:
Slip on a shirt, Slop on the 30+ sunscreen, Slap on a hat, Seek shade or shelter, Slide on some sunnies. — "Slip, Slop, Slap, Seek, Slide"By this stage, however, the skin cancer awareness message of the campaign had successfully been absorbed into the Australian psyche.
Slip, Slop, Slap (and Wrap) was also used in New Zealand, where the mascot is a lobster, voiced by Ants from What Now. Some Canadian cities have also started their own Slip-Slop-Slap campaigns. In Britain, it was used on the "BBC Breakfast Programme" 27 June 2011 with Bill Turnbull and Sian Williams.
