The FDA Carstens Memorial is important in demonstrating the high quality of the work of North Queensland monumental masonry firm Melrose and Fenwick. The decorative details on the memorial were likely executed by their artisan Harry Orton who was renowned for intricate relief work. The place has a special association with the life or work of a particular person, group or organisation of importance in Queensland's history. Erected in memory of Friederich Detleip Andreas Carstens, the memorial has a special association with the life and work of a man who contributed substantially to the advancement of the Port Douglas and Mossman region between 1886-1906, enabling the district to grow and prosper through his involvement with the Douglas Divisional Board and his role in promoting the construction of both the Mossman Central Mill and the Port Douglas and Mossman tramway.
