What was the legal jurisdiction / flag those planes were flying under?
A cruise ship under N'th flag, is under N'th legal territory, regardless of where on the planet it is.
It's why they check your passport at San Diego when you board a Norwegian flagged ship to go spend 3 days in Oregon. You step out of California, into Norway, even when that boat is still tied to the docks.
Does ICAO need to have a chat, using crayons, with Bondi?
