For the past 25 years, a group of up to 260 men and women - all dressed in distinctive blue and gold uniforms - have been the heart and soul of WA's favourite holiday island.
Made up largely of retirees, the Rottnest Voluntary Guides have done it all, from conducting island tours, holding quiz nights and even dressing up as pirates for school holiday activities.
Rottnest Island Authority chairman Laurie O'Meara described the guides as the island's greatest assets.
"For 25 years they have been a welcome sight on Rottnest," he said. "From a dozen individuals in 1986, the number of men and women prepared to regularly give of their time, expertise and enthusiasm is now over 260.
"The guides make a visit to the island more enjoyable."
Guides' president John Carroll said many of the guides had grown up on Rottnest and felt a real affinity to the island.
He said that, after retiring, many wanted to give something back to an island that gave them so much pleasure.
Colin Benporath, a retired satellite tracking operator, has been a guide for nine years and always looks forward to his shifts on the island.
He first came to the island in the 1950s, when he attended YMCA camps as a boy.
Guiding also allows him to work alongside his wife Beverley, who has been a guide for 10 years.
