Piara Waters Pavilion overlooks the playing fields and is used for sporting-club functions, community groups and private gatherings. The light-filled function area opens toward an outdoor canopy and playground.

Public directory and sports-club information identify a large function room for approximately 180 patrons, a kitchen with internal and alfresco serving points, and a separate meeting room. Club activity can limit access; one venue directory notes Saturday bookings are unavailable and excludes high-risk young-adult birthday functions. Verify the current public hire process and capacity with the City of Armadale before making plans.
