P&O Cruises Australia

P&O Cruises Australia was Australia's oldest and best-known cruise line — founded in 1932 as the Australian subsidiary of the British P&O Line and part of Carnival Corporation from 2003. Its headquarters were in Sydney. The brand stood for Australian cruising from home ports (Sydney, Brisbane, Adelaide, Fremantle): shorter voyages of three to fourteen days, a relaxed atmosphere, beer at Australian prices and an Australian crew.

The final fleet consisted of the sister ships Pacific Encounter (2002, ex Star Princess) and Pacific Adventure (2001, ex Golden Princess) — each 109,000 GT and carrying 2,640 guests. Both had previously sailed for Princess Cruises and were re-flagged to Australia in 2021. Itineraries focused on the South Pacific (Fiji, Vanuatu, New Caledonia), Tasmania, New Zealand and the Queensland coast.

The onboard language was Australian English and the onboard currency the Australian dollar. In 2025 the brand was absorbed into Carnival Cruise Line, ending nearly a century of P&O tradition in Australia. Pacific Adventure has sailed as Carnival Adventure ever since.
