Australia's famous opera house is in which city?

I've been there. I live in England, but my brother lives walking distance from Sydney Opera House.

Stephanie.S., The building of the Sydney Opera House started in 1959, a year before I went to Australia to live. It took 14 years to complete, due to general squabbling between the government, ( there had been a change of government before it was completed)the builders and the architect. When it was completed in 1974 the cost was A$102 million the equivalent now would be approximately A$1082 million

That's on my bucket list 😎.
