8 Night Queensland Cruise

Sydney, capital of New South Wales and one of Australia's largest cities, is best known for its harbourfront Sydney Opera House, with a distinctive sail-like design. Massive Darling Harbour and the smaller Circular Quay port are hubs of waterside life, with the arched Harbour Bridge and esteemed Royal Botanic Garden nearby. Sydney Tower’s outdoor platform, the Skywalk, offers 360-degree views of the city and suburbs.

Willis Island is the only permanently inhabited island in the Coral Sea Islands Territory. Located beyond the Great Barrier Reef, this island stands 280 miles from Cairns. The only residents on the 7.7-hectare sandy island are a handful of Australian Bureau of Meteorology staff members working at the weather monitoring station.The main attractions are the sights you'll see as you cruise through the Coral Sea. Spot tropical birds like black noodies, sooty terns and wedge-tailed shearwaters. Cruise to Willis Island to see the Great Barrier Reef stretch beneath the turquoise waters and the exotic fish that swim here, including angel fish, clown fish and hammerhead sharks.

Situated in tropical north Queensland, Cairns is the gateway to the Great Barrier Reef and Daintree Rainforest. These two UNESCO World Heritage Sites are why Cairns is the fourth most popular destination for international tourists in Australia. Enjoy the city's year-round tropical summer weather as you relax beside the man-made lagoon on the Esplanade. Then, experience one of Cairns' two main drawcards: Head into the rainforest in nearby Kuranda, which you can reach by taking the Skyrail Cableway or the Scenic Railway. Cruise to Cairns and take the half-day trip to Green Island — you'll be snorkeling on the Great Barrier Reef within an hour of leaving the city.

Airlie Beach is the Queensland coast's go-to spot for maritime adventure. It's the mainland town that allows the easiest access to the 74 incredible Whitsunday Islands — take the ferry out and spend your day relaxing by clear aqua waters at Whitehaven Beach or snorkeling among the heart-shaped portion of the Great Barrier Reef, a UNESCO World Heritage Site. Or stick to the mainland: Walk the Bicentennial Walkway along the Airlie Beach waterfront, popping into a cafe for a late-morning flat white (the Australian signature latte). Take a dip in Airlie Beach Lagoon, or head to Conway National Park, where you can hike your way through rain forest to panoramic views of the city and the harbor.
