Top it all off with a laid-back

A Wet Tropics World Heritage Area, Daintree National Park in Far North Queensland is among the most ancient ecosystems on Earth. The area belongs to the Eastern Kuku Yalanji Aboriginal people, and many of its natural features hold great spiritual significance.

A word to the wise: If you're taking a dip at Bondi, make sure you swim between the red and yellow flags. Strong rip tides often sweep unsuspecting swimmers out to sea, especially at the southern end of this kilometer-long strand. There's a reason the Aussies made a reality TV show called Bondi Rescue.

Bronzed bodies, blond sand, backpackers, and surf — throw it all together and you get one of the world's most famous beaches. Only 15 minutes by car from Sydney's city center, Bondi Beach is a great spot for a taste of Sydney's beach culture. Bask on the golden sands, surf the breaks, or take a cool dip on a hot summer's day (but stay between the flags).

Melbourne, Australia's second-largest city, is a popular stop on many Australian itineraries — especially for culture vultures. Galleries, theaters, restaurants, shops, and its distinctly European feel are the main draws of this sophisticated city on the Yarra River.

The most famous attractions in Blue Mountains National Park are the towering sandstone rock formations called the Three Sisters. Other highlights include the Katoomba Scenic Railway, the world's steepest, which whisks passengers down the Jamison Valley through a cliff-side tunnel into an ancient rainforest; and the Skyway, Scenic Cableway, and Scenic Walkway, which all offer elevated views of the dense forests.

Named for the blue haze emanating from the many eucalyptus trees, this stunning park protects more than 664,000 acres of wilderness. On a visit here, you can explore dramatic gorges, waterfalls, Aboriginal rock paintings, and 140 kilometers of hiking trails.

Along with the Opera House, the Sydney Harbour Bridge is one of Australia's top architectural icons. Affectionately called "the Coathanger," this impressive feat of construction is the largest steel arch bridge in the world. It was completed in 1932, 40 years before the Sydney Opera House.

Also in the park, about a 30-minute drive from Uluru, are the red dome-shaped rocks called Kata Tjuta (formerly called the Olgas). Equally impressive as their more famous neighbor, and often less crowded, they should not be missed while you are in the park. You can admire their beauty on the 2.6-kilometer-return trek to Walpa Gorge or the 7.4-kilometer Valley of the Winds circuit.

Not surprisingly, the Great Barrier Reef is one of the best places to visit in Australia for diving and snorkeling. The astounding array of marine life includes soft and hard corals, more than 1,600 species of tropical fish, sharks, dugongs, dolphins, turtles, rays, and giant clams. Prefer to stay dry? You can see the reef from underwater viewing stations and glass bottom boats.

In 1975, the Great Barrier Reef Marine Park was established to protect its fragile ecosystems. These include more than 3,000 coral reefs; 600 continental islands, including the beautiful Whitsunday group; 300 coral cays; and inshore mangrove islands.
