Sydney Christmas Holiday Help

I am a professional photographer and plans on going to Sydney during Christmas break. I have searched all over for a plan that would fit my need of taking pictures and images, but none really worked. Thus, I came for the power of reddit. I would really appreciate it if you guys can give me some advices and plans and photo spots for my trip. For even more context, I shoot landscape and street photography mostly. I would love photo spots that have less people so that I can guide the attention to the main subject(Except for street since it focus on the PEOPLE) For example, people always tell me to go to circular quay, but there has to be a huge amount of tourists there especially during Christmas break, so I wonder if there are any other good spots with the same or even better view? Once again, thank you to everyone who gave me advices!
