Pacific Explorer

Pacific Explorer (previously known as Dawn Princess) is a cruise ship operated since June 2017 by P&O Cruises Australia, a cruise line brand owned by the Carnival Corporation & plc. It is a Sun-class cruise ship built by Fincantieri, Italy, in 1997, and features eight restaurants, four swimming pools, five hot tubs/spas/whirlpools, seven lounges and bars, and two children centres.

She is the sister ship to MS Sun Princess, P&O Cruises' MV Oceana (former Ocean Princess) and Sea Princess. Pacific Explorer and Sun Princess differ from Oceana and Sea Princess by having exterior bridge wings. Oceana and Sea Princess have internal bridge wings.

As part of the announcement that P&O cruises would merge with Carnival, it was revealed the Pacific Explorer will not be joining the Carnival fleet and will be withdrawn in February 2025. The future of the ship is yet to be known.

Ports of call
Dawn Princess was targeted to replace Pacific Princess, sailing Australian waters between October 2006 and March 2007, to become the largest ship ever to be based in Australia, but these plans were eventually replaced by Sun Princess as well as being served by  Pacific Dawn (previously christened Regal Princess). Dawn Princess began sailing in Australia as of 24 September 2008 with a 28-day itinerary circumnavigating the country, after a month serving Hawaii, Tahiti, and the South Pacific. From this point on, Dawn Princess remained in Australia permanently sailing from Sydney, Melbourne and Perth alongside Sun Princess under the Princess brand until it was transferred to P&O Cruises Australia and renamed Pacific Explorer.
