That's not at all true. It has been decimated due to our lockdowns and restrictions. We are going to be rebuilding the industry over the next several years. We are not "saturated" but we have increasingly more options with cruising being more and more popular pre-covid. We sail the premium and boutique cruise lines like everyone else. Disney wouldn't be registering for GST if they had no intention of sailing here in the not too distant future. That said, things can change based on market and global conditions.
Pre COVID, Australia was the highest penetrated cruise market in the world - meaning it sported the largest proportion of population that was already cruising. That's what I mean by saturation.
The premium cruise lines sail down under for roughly four months a year. The majority of those cruising on the premium lines aren't Australians. They are global travelers - North Americans, Europeans, Japanese, even Chinese, and, yes, Australians too. Many are looking to spend their northern winters in the southern hemisphere and like to cruise with their familiar brands.
How much market there is going forward is a good question. Long-distance air travel remains very tricky for many cruisers. Celebrity, HAL, and NCL, for example, were all committing two ships to the Australian summers before COVID, but now it's down to one each until 2024. Princess in 2019 had five ships down under - and now it's 3 or 4. (It may all rebound at some point, yes.)
Disney faces the additional issue of having to appeal to families. Can it fill the Wonder six times over every month with its prices just from Australia? A country smaller than Canada? Not really. At least not in a way that can be sustained every year. It needs to bring families over from the northern hemisphere.
Maybe with all seven ships running, Wonder ventures beyond Hawaii. Right now, even the timing of a return to Hawaii is uncertain.
As I noted, there are reasons for registrations. Whether it's for quoting AUD fares, setting up an Australian company to manage locally sourced employees, doing a tie-up with ABD tours, marketing Hawaiian packages when the Wonder is in Honolulu, or, yes, cruising in Australia. Of these, cruising down under is the least likely scenario for now. It may change after Triton III is sailing - but 2023, as the video claims, is quite a stretch.
