The memorial consists of a bronze sculpture of Simpson and his donkey mounted on a piece of the trunk of the original Inverell Lone Pine, which was cut down in 2007 because of safety concerns. The artwork is accompanied by several interpretive signs. In front of the sculpture is a plaque bearing a dedication to those who served and died in the First World War. On either side of the sculpture are panels, which tell the story of the Lone Pine seedlings. The final sign is listed separately on the NSW War Memorials Register as the Inverell R.S.M. Club Lone Pine Story Board. The memorial is located inside the Inverell Returned Servicemen's Memorial (R.S.M.) Club and access to it is restricted to the opening hours of the club. Another Inverell Lone Pine is located in nearby Victoria Park.
