From 1975, Australis was the title of the world's largest express ship, simply because they already had one of the last remaining large ships with this task at this time.
In 1977, she was the last remaining ship that brought immigrants to Australia in scheduled liner service.

Deprived of her task, there was no choice but to lay up Australis. This happened in November 1977 after her last trip to Timaru, New Zealand where the ship waited for a buyer while few visitors came to visit on board, among them veterans of USS West Point.
There were rumors that the ship should be scrapped, or as a hotel ship would get a new job, but ultimately it was then for a good price on 18 May 78 sold to an American consortium that was planning to get Australis as a passenger ship.
