Seabourn is to visit the Kimberley region of Australia for the first time next year.
A series of six 10-day voyages to the region between Broome and Darwin will be run by expedition ship Seabourn Pursuit in June, July and August 2024.
The ship will also visit Papua New Guinea, Indonesia, and sail to the South Pacific from Chile to Melanesia between March and October 2024.
Sister vessel Seabourn Venture will return for another season in the UK, Ireland, Norway, Greenland, Iceland and the Canadian Arctic.
Both ships will sail to the Antarctic at the end of 2024 and early 2025.
The details for the pair of vessels, which each have 132 suites, come in a new sailing programme for summer and winter 2024 and spring 2025.
Robin West, vice president and general manager of expeditions, said: “These new expeditions are going to be thrilling and offer so many opportunities for guests to discover the natural and cultural wonders found in some of the farthest corners of the planet, including our first-ever visit to the Kimberley in Australia.
“Best of all, guests will be experiencing everything in the company of expedition team members who will bring the wonders of each destination to life.”
