Allan was been a Rotarian since 1968 when he joined the Rotary Club of Sandgate, Newcastle, New South Wales, Australia. He was instrumental in founding Sustainable Cambodia Australia (SCA), a group formed with the support of the Rotary District Governors in Western Australia, Districts 9455 and 9465, based on a shared vision of self-help and sustainability.  Through Allan's efforts and those of the numerous Australian Rotarians he has inspired, SCA works with Sustainable Cambodia's education and village development programs. He led many groups of Rotarians who came to Pursat to help build the programs, and he was instrumental in the high protein meals given each school day in numerous SC preschools. He provided educational and school materials to SC primary and preschools, desks, chairs, teachers, materials and books. Through the SCA Sister Village projects that he fostered, village families were helped with wells, water filters, animal pass-ons, vegetable gardens and fish ponds. Allan is sorely missed, but his impact on thousands of lives will live on beyond him and he will be part of SC family forever.
