Avalon Annexe is a council-listed 100-person function and community space associated with Dunbar Park at Avalon Beach. Northern Beaches Council's facility comparison identifies it as suitable for functions, with accessible features and an adjoining play area, but not for jumping castles or 18th/21st birthday celebrations. Current references to its location are inconsistent: an older council directory gives 3 Bowling Green Lane, while contemporary event information describes an Annexe at Dunbar Park near 59 Old Barrenjoey Road. Use the park-level map location for now, and confirm the correct hall entrance and precise street number with council before directing visitors or publishing an exact address.
