If anybody abroad is interested in watching Serenade's sail-in / sail-out of Sydney Harbour, https://webcamsydney.com/ has got you covered. They have prime viewing over the harbour and Opera House. Serenade will be tendering from arrival until 2:00 pm (local time) since another ship is docked at the Overseas Passenger Terminal, so you won't be able to see them on the webcam. But then from 3:00 pm (11 pm EST) until Midnight (8 AM EST tomorrow), they will be docked there, so that's the best time to watch. I'll try to capture some images if I can, though of course those on the ship get the best view of all. 😆
This is Serenade's tender / docking schedule for Sydney, which I mentioned above.
