Aldinga Institute Hall is a heritage community venue at 23 Old Coach Road in central Aldinga. City of Onkaparinga describes polished timber floors, a theatre-style stage and large kitchen, with tables and seating available for local celebrations, classes and community gatherings. The current hall traces its history to the 1935 replacement of an earlier institute building and retains the character of a traditional town hall. Council lists accessible facilities, heating, air conditioning and parking, but the approved guest limit is not clear on the public page.
