The Sydney Opera House is keen to be inclusive with their performances, and activities. Accessibility Program Manager, Jenny Spinak, has spearheaded much of the progress in creating an inclusive program. The Accessibility page of their website has more than just information on how to access the building and parking. With the upcoming winter lights festival, Vivid Sydney, the Opera House is staging several accessible performances with audio description and Auslan interpreters.
Previously the Sydney Opera House included an autism-friendly performance of the musical The King and I. You can see more in the video link below.
