Well it is possible. A cruise might be considered clean if HK's 21 day quarantine does its job and there are no passenger pick up in Bali, and they are at sea for more than 14 days with no new cases arising.Our beloved folk in the LOTF just make me want to bang my head on the computer. On a Cruise ship forum, for a trip from Hong Kong through Bali through to Sydney later this year. With comments like "well, I will have had two shots of the vaccine by June so of course I will be allowed on this cruise to Australia". I have given up explaining realities to them. Let them hand over their thousands of dollars of fares.
Who knows? There might be enough celebrities on board to get a specific exemption for the cruise.
