'Prepare for an uproarious "Orphan's Christmas" when Sydney Opera House presents an adults-only panto from the writing team that brought you the smash hit Fat Swan and the director of Smoke & Mirrors.

Ten-year-old little orphan Fannie (Trevor Ashley), has a terrible secret... one that she can't even share with her inmates at the Sutherland Shire Girl's Orphanage, let alone the boozy matron who runs the place: the evil Miss Trannigan (Rhonda Burchmore). The truth is: Fannie is not yet all woman. But, to get her gender-reassignment surgery, she'll have to find her true birth parents to get their permission.

Lucky for Fannie, she meets acclaimed photographer / multi-millionaire Daddy Warhorse (Gary Sweet) who promises to sponsor her! But can she survive a rigorous set of blind auditions, a very "arty" photo shoot and an appearance on evil talk-back radio personality Ellen Jones' show before she finds her parents?

To make her wish come true, Fannie may need more than just her trusty ex-sniffer dog Bullshit (Rhys Bobridge)... she may need a Christmas miracle!' (Source: Sydney Opera House website)
