The line will see five ships travel to more than 100 destinations carrying 200,000 passengers, departing from Sydney, Perth (Fremantle), Adelaide, Melbourne, Brisbane and Auckland.

Itineraries will include ports of call in Australia, New Zealand as well as Singapore, Hong Kong, Fiji and Bali.

The season will see the return of the 3,560-passenger Majestic Princess, the line’s newest ship, to the region as well as the maiden arrival of the 3,100-passemger Ruby Princess. Both vessels will sail out of Sydney.

In south Australia the 2,600-passenger Golden Princess and 2,000-passenger Sun Princess and Majestic Princess will offer itineraries to and from Adelaide.

Tony Roberts, Princess Cruises’ vice president UK and Europe, said: "UK bookings to Australia have nearly doubled year-on-year in 2018 so it’s fitting we’re now gearing up for our largest ever Australia and New Zealand season.

“We’re anticipating an increase in UK visitors to the west coast of Australia, including historic Perth and its stunning coastal setting, and have ensured we’ll spend more time there so guests can take advantage of everything the region has to offer.

“From Sydney Opera House to the Great Barrier Reef to our ‘Lord of the Rings’ tours in New Zealand we have unprecedented choice for anyone looking to sail across this stunning part of the world.”
