The RAOLC was started after the Imperial Services Club (ISC) closed down in Sydney and was subsequently Incorporated into the RACA in 1986.  Two Regular Army Officer friends who dined together on a regular basis at the ISC then lunched at the RACA. They then invited a list of Regular Army Officers to join them. By agreement with the RACA the RAOLC was born. Members of the RAOLC do not have to be members of the RACA to attend lunches.

The RAOLC has always been for serving and retired Regular Army Officers (men and women) and their occasional guests. On limited special occasions and by mutual agreement, other service related organisations and commemorative events may join the RAOLC for lunch. These may include events such as Military Anniversaries, RMC Duntroon Graduations and book launches  on military topics. These are often arranged through RACA Functions but may be initiated by the Convenors of RAOLC.

Meetings: The RAOLC meets on the second Friday of each month, excluding January. The normal venue for the lunch is the ISC Room on Level 4 of the Club. Members meet in the Members bar on Level 3 from 1200hrs. Bookings may be made by telephone to 02 8273 2320 or by email to Events@raca.com.au and should be in by C.O.B on the Wednesday before the event. An email reminder in a newsletter format is sent out to all registered members before the event. Members may also be advised of other significant news by this means from time to time.

A Melbourne Cup Function which includes wives/partners is also part of the RAOLC Calendar. Arrangements are usually announced in September/October and bookings are on a first come first served basis due to limited seating.
