CMV has bought the Astor after operating the cruise ship under a charter agreement since December 2013.
The 600-passenger ship will continue to operate ex-Fremantle cruises under the CMV brand for the Australian market during the Austral summer season.
In spring 2015, Astor moves to Europe for a summer season of ex-Kiel and Bremerhaven German market sailings under the TransOcean brand.
Christian Verhounig, CEO and chairman of CMV said: "The acquisition of the Astor is another important milestone in the strategic development of the Group’s presence in the international markets."
Chris Coates, commercial director said: "Astor has added 22,000 passengers to our global carryings and since her introduction has proved a firm favourite with high levels of customer satisfaction and repeat business being achieved.
"Next year we have programmed a special 8 night ex-London Tilbury Round Britain cruise before Astor starts her German market season and forward booking levels are very encouraging".
