It’s likely Quantum of the Seas will cruise from Singapore to Brisbane in November 2024. She is due for dry dock and the work will probably be done in Singapore. There is an entry in Darwin port calendar for Nov 24, 2024. Quantum’s first entry in Brisbane’s port calendar for that season is Dec 1, 2024.
Ovation is also due for dry dock in 2024 but I don’t know what theur plan is.
