I remember, in my foggy brain, Carnival Spirit was delayed for a considerable time from entering Sydney Harbour due to bad weather. I am sure it was less years ago than 2012. Cheers, Buzz.
Definitely 1500 flight, we have disembarked in Sydney many times and have had delays in arrival time back in port. Then it depends if our Border Force are operating smoothly or in chaos as happens sometimes. Enjoy your cruise, cheers, Buzz.
