21 performances each. OAO also appears in gala concerts and special events such as Mazda Opera in the Domain and the New Year's Eve Gala Concert in the concert hall of the opera house. In 2012 OAO appeared in Opera Australia's first event presentation of Handa Opera on Sydney Harbour in 18 performances of La traviata, using a purpose-built floating stage and orchestra pit, moored in Sydney's Farm Cove opposite the Sydney Opera House, sponsored in part by the International Foundation for Arts and Culture. Most years since there has been a new production: Carmen, Madama Butterfly, Aida, Turandot, with Carmen restaged in 2017. OAO averages under 10% of Opera Australia's annual running costs.
