Princess Cruises has agreed to sell Sun Princess and Sea Princess.
Deals have been negotiated with undisclosed buyers, Princess has confirmed.
The sales come as part of parent Carnival Corp’s efforts to speed up disposal of less efficient ships.
Sun Princess, Princess’s first Sun-class ship, debuted in the Caribbean in 2005, and went on to sail Alaska and the Panama Canal.
It homeported in Australia in October 2007 before being used to launch Princess to the Japanese market in 2013.
Sea Princess, meanwhile, has long been associated with Princess’s world cruise programme, completing six full world cruises since 2013 and travelling the equivalent of 35 times around the world.
Prior to being deployed in Australia alongside Sun Princess, Sea Princess sailing in Europe, Alaska and the Caribbean, homeporting in Barbados in the mid-to-late-2000s.
