Well....it's an iconic building and has to be visited, sorry we couldn't book a performance..
Good English speaking tour guide made it an interesting and very pleasant hour. You have to do it...!

Almost all the reviews about this tour are correct. Our lively animated Alex was a delight to be with the entire time. You will learn pretty much anything you want to ask about the construction of estimated $7 mil and ended up $102 mil and 16 yrs. to build and disputes among architects and politics and now being renovated again for hundreds of mil. Opera is not the only type of show. Five different theaters and 5 different types of shows can run at the same time. You will the types of performers and what demands they make in contracts before they will perform. The lifts and green room and different rooms you will visit will be fascinating. The guide will let you take pictures only in specific spots but not staff people.

I watched the Antony and Cleopatra show (7.30pm) on Thur 15/3/18 at the Sydney opera house. The show was great and the theatre itself was amazing also. Loved every second. Definitely would recommend to pay the bit extra and to go watch a show in the opera house instead of just paying for the tour of the opera house.

We are visiting friends (locals) and they suggested the guided tour. It was awesome! Our guide Bruce was dry knowledgeable, funny and good with all ages. We saw four performance areas and learned a lot. Plan on 90 minutes from check in to check out.
