Morundah is notable for its recent tradition of hosting opera performances, including the touring arm of Opera Australia, OzOpera's performance of Carmen in 2006 and the performance of Cosi fan tutte by the Victorian Opera in 2007. In 2012, Co-Opera's performance of Die Fledermaus was very well received.
In 2016, the old "opera house" -- which was basically a prefabricated pig shed -- was demolished and replaced by a larger permanent structure, designed to cater for not only opera, but a range of other types of events.
