In 1932, WW1, veterans and friends formed the Hills District Returned Soldiers and Sailors Club. On 27 August 1942, they formally constituted as a Sub Branch of the Returned Sailors League of Australia.

 Membership swelled at the end of WWII to over 1,200 members. Initially, the Sub-branch operated out of a Dug Out and an attached Army hut from the 113 Army General Hospital. Although at that time, it was pretty much a sly grog venue tolerated by the police.

 It became a licensed venue in 1956 after the first stage of the new club was constructed on Sub-branch land where the ANZAC Hall once stood.

 In 1974, the current club was built and occupied. In 2001 the club was purchased by the Castle Hill RSL Club Limited.

 Since our Sub-branch began, it has continued to support veterans with families in need. Formally trained veterans assist members seeking pensions from DVA. Another welfare officer group regularly visits hospitals and retirement villages to help veterans.

 Our Sub-branch will celebrate our 80th anniversary on 27 August 2022 with a lunch attended by the NSW Premier and other distinguished guests.
