In December, Silversea Cruises will return to Asia for the first time in over a year.

The Silver Muse will be the first cruise ship to return to Asia when it leaves Singapore on December 2. The ship will be joined in the region by three other vessels.

After more than two years, the Holland America Line returned to Australia this week, with the first ship to come back being the Westerdam. The ship will stop at Airlie Beach and Moreton Island in Australia before heading to Australia. Part of the ship's 2022-23 Australia and New Zealand season will take place in Sydney.

Cruises are filling up

The president of Holland America said that despite only opening sales for the Westerdam in Australia seven months ago, they are already seeing full cruises in the region.

Australia circumnavigation cruise will be offered by the Noordam. The first season of the Westerdam in Australia and New Zealand will be the first time since 2016 that Holland America Line has put two ships in the same region.
