Eternity Playhouse is a purpose-built performance theatre in a heritage building at 39 Burton Street, Darlinghurst. The City of Sydney advertises a 200-person capacity and describes it as a venue for professionally produced theatre seasons, concerts and cultural events. The council’s indoor-hire page lists approximately 800 m² for the facility and asks that enquiries be lodged with at least eight weeks’ notice. Previous maintenance works ended in August 2025, but a separate project page specified a hire period ending June 2026; as the current date is later, future public availability and management arrangements should be confirmed before treating a booking as possible.
