The State Library of NSW Auditorium is a purpose-built, tiered theatre for film screenings, lectures, conferences and large presentations. Set beneath the Mitchell Library Reading Room, it provides 344 fixed seats, a large cinema screen, 4K laser projection, surround sound and microphones. Two greenrooms support speakers and performers, while the adjoining Glasshouse can be used for reception, catering or registration activity. This pairing is well suited to events that need a professional presentation environment followed by networking or refreshments.
