Wild weather caused the cancellation of Opera on Sydney Harbour's production of Aida on Tuesday, but organisers are more concerned by damage caused to the outdoor set by "bloody cockatoos".

Opera Australia's chief executive Craig Hassall said the site was shielded from the worst of the weather.

"Most of the wind is coming form the east and because we're tucked below that hill, it's actually quite protected," he said. "I was concerned the big Nefertiti head might wobble a bit but apparently it's fine apart from bloody cockatoos."
