Quantum dry dock is in Singapore this November, which is why there's no TP from Hawaii - Brisbane this year. The Ovation Hawaii - Vancouver which you've screenshotted will almost certainly be either cancelled or swapped to Quantum, as Ovation is not doing Alaska in 2025. Rumours in Australia are Ovation could be heading back to Asia. Quantum is showing up in the Sydney port bookings for a one off in mid-April 2025, so may well be doing Brisbane-Sydney-Hawaii for her TP.
