The Rathmines RAAF Base is on the western shore of Lake Macquarie. The design and construction of the base at the beginning of the Second War resulted in a geometric layout of structures over the site which reflect its use for military purposes. When the base closed in 1956, there were more than 230 buildings and structures on site. In 1997, ten remained: • The officers mess, adapted for use as the Rathmines Bowling Clubhouse • Part of the north-east hangar, adapted for use as the Christadelphian School • The inflammable liquids store, adapted for use as the Scout Hall • Substation No.2, now empty and not in regular use • The airmen's ablution building, adapted for use as Rathmines Catamaran Clubhouse • The picture theatre and gymnasium building, adapted for use as Rathmines Community Hall • The central boiler house, now stripped and used as a store • The emergency power house, now stripped and used as a store • The sergeants mess, adapted for use as Westlakes Music Centre • The base hospital and facilities, now owned and operated by Disability Life Enrichment Ltd and incorporating the Catalina Conference Centre. In 1997, the former picture theatre and gymnasium was the most intact of all the surviving structures and had the most original fabric. It was one of the base's largest, most important buildings. The cinema hall is the largest in volume with a stage flanked by dressing rooms at the north-east end. Beyond is the former gymnasium, though it has been altered and subdivided. Other structures also on the site in 1997, many altered or adapted, include: • A concrete stormwater channel • The bomb and fuel wharf, partly rebuilt • Part of the Marine Section timber wharf, now rebuilt as the "F" wharf • The jetty and slipway complex at Styles Point • The concrete
apron area • The bitumen hardstanding • The parade ground • The first septic tank installation • The second septic tank installation In 1997, there were also many remains of structures on site, including: • The pump house and duty pilots tower • The general stores building • The celestial trainer • The aircraft stores • The motor transport building • The parade ground saluting base • The central ironing room and laundry • A remnant of the south boundary fence • The battery room • The western hangars
Condition In 1997, there was a significant amount of remaining physical evidence from the war time use of the Rathmines Base. The elements which remained varied in condition. Some have been largely altered and adapted for new uses, and some are in disrepair. There are two Aboriginal Artifact Scatters (one scatter and one isolated find) and a midden recorded within the area.
Modifications and dates Following sale in 1962, several structures were leased: picture theatre and gymnasium for Rathmines Community Hall; flammable liquids store for Scout Hall; airmen's ablution block for Sailing Club; officers' mess for Rathmines Bowling Club; sergeants' hall for Westlake Music Centre. The base hospital was sold to private interests and the workshops to a Bible School. Many buildings were also sold and removed. The Catalina Memorial was constructed on the site in 1972. == Heritage listing ==
