The memorial club building was formerly the Officers' Mess of the Rathmines Royal Australian Air Force (R.A.A.F.) base. Inside the club is a memorial wall. On the wall are photos with details of each of the R.A.A.F. seaplanes used during the Second World War. A leadlight panel depicts a Catalina amphibious aircraft and there is also a dedication plaque, a plaque about the Officers' Mess, a list of seaplane units and a list of personnel. Hanging from the ceiling are various model aircrafts.
