This mega-yacht, Apoise was moored in front of the Park Hyatt at Circular Quay over New Year’s; they would have had a pretty good view of the fireworks.
Apoise is 67m long, which just pushes it out of the top 50 yachts in the world; the shortest yacht on that list is 72m. It’s impossible to tell who owns Apoise. The owners are listed as some Cayman Island company called Apoise Holding, Pty Ltd. Which tells you nothing.
