Cairns Sunboys is a social group which provides men an opportunity to be nude with other guys. Sunboys is neither a club nor an organisation, just a group, and it is open to men from all and any walks of life. There are no restrictions regarding shape, size, ethnicity or sexuality. The only requirement is that participants be over 18 years of age and agree to the strict no sex policy at group functions.
In the early 2000s Michael Moore ran a website advertising Cairns Sunboys, a group no one seemed to know anything about, and about which Michael himself was always evasive. In 2010 Graham Payne challenged him, asking when and where the last meeting had been held. Michael admitted that there had never actually been a meeting.
