18 Night Cruise sailing from Perth to Sydney aboard Radiance of the Seas.

Royal Caribbean's Radiance of the Seas offers the ultimate "at sea" experience by combining speed, added comfort, greater open spaces, sweeping ocean vistas and an exceptional cruise staff committed to serving your every whim.

Highlights of this cruise:

Perth
Perth, the capital of the state of Western Australia, is the fastest growing major city in Australia, with a population of over 1.5 million people. Situated alongside the tranquil waters of the Swan River (named for the indigenous population of Black Swans), much of Perth's growth and vitality is due to its proximity to surrounding natural resources, including gold, iron, diamonds, oil and natural gas.

Albany
Whales, wine and wildflowers beckon in Western Australia's oldest and prettiest town. In fact, some consider its rugged and cliffy coast to be some of the most scenic in the entire world. Albany is also aesthetically privileged with two incredible waterways, the stunning King George Sound and Princess Royal Harbour. And these once whaling waters are now a playground for humpbacks and dolphins. It's not unusual to spot some frolicking by the shore. So keep your eyes on the ocean and your camera on zoom!

Adelaide
This easy-going capital of South Australia is your portal to every big outdoor adventure you could dream up. Trek the raw, rugged Outback in all its aboriginal glory. Hop over to Kangaroo Island, one of the world's best places to view wildlife, hence the name. Then hit the wine trail with glass in hand! Adelaide is in the thick of the country's finest vineyards. Don't feel like venturing out? The city center offers a wide array of excitement from architecture and art galleries to gourmet goodies. And if you happen to be in town during one of the many festivals, you don't want to miss out. People come from all over the world to participate in the funtivities. So make sure to be one of them!

Melbourne
Sitting pretty in the southeast corner of Australia is the very multi-dimensional Melbourne. Whether you're into football or funky fashion, local pubs or chichi cafes, out there or traditional architecture - this epicenter of everything truly has it all. Including a rich and notorious past. You'll find traces of it all over, from the Old Melbourne Gaol (one of the many Australian jails) to its many museums. Today it's considered one of the world's most livable cities. So pack accordingly.

Hobart
There are few places as tranquil as the island of Tasmania. So it's no surprise that Aussies head here for a taste of laid-back island life. Over a third of the landscape is covered with national parks and wilderness World Heritage areas. It's even home to one of the world's best beaches and tons of aboriginal creatures such as the short-beaked echidna, little pygmy, and yes, the Tasmanian devil himself. And Hobart, the island's Europeanesque harbor town, is the perfect prequel to it all.

Dunedin
As gateway to Queenstown's many adrenaline-pumping activities and guard to the unspoiled natural habitats of the Otago Peninsula, Dunedin, the second-largest city on the South Island, with its historic Victorian architecture, alternative collegiate vibe and outstanding outdoor recreation, stands second to none. Whether you want to peep at rare penguins, view historic buildings or take in a museum, Dunedin has it all and then some.

Wellington
The fact that Wellington has become New Zealand's fastest-growing weekend destination tells you something about the city. Once merely its political capital, the city's calendar is packed with celebrations, festivals and some of the country's best theater and dance. Sandwiched between steep hills on one side and the ocean on the other, New Zealand's second-largest city is a walker's paradise. Because so much of the city is within walking distance, you'll never feel the need to hire a cab. And considering the number of cafes, bars and nightclubs that line the streets, you'll probably never feel the need to go to bed, either.

Sydney
The whole world's in love with Sydney. It's stylish, it's sophisticated, it's home to some of the friendliest people on the planet. And yes, a few koalas, if you know where to look. What's not to love? This gateway to the Outback has it all: endless outdoor adventure around the harbor or in spots like the Blue Mountains. Golden sandy beaches named Bondi, Bilgola and Coogee (which are not only beautiful, but also fun to say). A bustling art and entertainment scene. Countless museums, galleries and world-class restaurants where the dishes go way beyond the local Vegemite.
