2021 Australia/NZ cruise schedules - when are they likely to be released?

Hi ya, am off on Golden Princess again in a couple of weeks, then have a short cruise on Ruby Princess Dec 2019......

Probably won't be able to cruise again until 2021.

Given the knowledge base on these forums, I'm hoping one or more of you can give me some idea of when schedules are likely to be released for last half of 2021.

Turning 60 that year, so absolutely MUST do another cruise to celebrate:D and I will want to book as soon as dates are released!

Thanks:D

They have just released the 2019/2020 cruise schedules, so I would think the 2021 cruise schedules would be released in about August / September 2019.
