Consistently rated among the "world's most livable cities" in quality-of-life surveys, Melbourne is built on a coastal plain at the top of the giant horseshoe of Port Phillip Bay. The city center is an orderly grid of streets where the state parliament, banks, multinational corporations, and splendid Victorian buildings that sprang up in the wake of the gold rush now stand. This is Melbourne's heart, which you can explore at a leisurely pace in a couple of days.In Southbank, one of the newer precincts south of the city center, the Southgate development of bars, restaurants, and shops has refocused Melbourne's vision on the Yarra River. Once a blighted stretch of factories and run-down warehouses, the southern bank of the river is now a vibrant, exciting part of the city, and the river itself is finally taking its rightful place in Melbourne's psyche.Just a hop away, Federation Square—with its host of galleries—has become a civic landmark for Melburnians. Stroll along the Esplanade in the suburb of St. Kilda, amble past the elegant houses of East Melbourne, enjoy the shops and cafés in Fitzroy or Carlton, rub shoulders with locals at the Victoria Market, nip into the Windsor for afternoon tea, or rent a canoe at Studley Park to paddle along one of the prettiest stretches of the Yarra—and you may discover Melbourne's soul as well as its heart.

Sydney belongs to the exclusive club of cities that generate excitement. At the end of a marathon flight there's renewed vitality in the cabin as the plane circles the city, where thousands of yachts are suspended on the dark water and the sails of the Opera House glisten in the distance. Blessed with dazzling beaches and a sunny climate, Sydney is among the most beautiful cities on the planet.With 4.6 million people, Sydney is the biggest and most cosmopolitan city in Australia. A wave of immigration from the 1950s has seen the Anglo-Irish immigrants who made up the city's original population joined by Italians, Greeks, Turks, Lebanese, Chinese, Vietnamese, Thais, and Indonesians. This intermingling has created a cultural vibrancy and energy—and a culinary repertoire—that was missing only a generation ago.Sydneysiders embrace their harbor with a passion. Indented with numerous bays and beaches, Sydney Harbour is the presiding icon for the city, and urban Australia. Captain Arthur Phillip, commander of the 11-ship First Fleet, wrote in his diary when he first set eyes on the harbor on January 26, 1788: "We had the satisfaction of finding the finest harbor in the world."Although a visit to Sydney is an essential part of an Australian experience, the city is no more representative of Australia than Los Angeles is of the United States. Sydney has joined the ranks of the great cities whose characters are essentially international. What Sydney offers is style, sophistication, and great looks—an exhilarating prelude to the continent at its back door.

Founded in 1824 on the banks of the wide, meandering Brisbane River, the former penal colony of Brisbane was for many years regarded as just a big country town. Many beautiful timber Queenslander homes, built in the 1800s, still dot the riverbanks and inner suburbs, and in spring the city's numerous parks erupt in a riot of colorful jacaranda, poinciana, and bougainvillea blossoms. Today the Queensland capital is one of Australia's most up-and-coming cities: glittering high-rises mark its polished business center, slick fashion boutiques and restaurants abound, and numerous outdoor attractions beckon. In summer, temperatures here are broilingly hot and days are often humid, a reminder that this city is part of a subtropical region. Wear SPF 30-plus sunscreen and a broad-brimmed hat outdoors, even on overcast days.Brisbane's inner suburbs, a 5- to 10-minute drive or 15- to 20-minute walk from the city center, have a mix of intriguing eateries and quiet accommodations. Fortitude Valley combines Chinatown with a cosmopolitan mix of clubs, cafés, and boutiques. Spring Hill has several high-quality hotels, and Paddington, New Farm, Petrie Terrace, West End, and Woolloongabba are full of an eclectic mix of restaurants and bars. Brisbane is also a convenient base for trips to the Sunshine and Gold coasts, the mountainous hinterlands, and the Moreton Bay islands.

Tourism is the lifeblood of Cairns (pronounced Caans). The city makes a good base for exploring the wild top half of Queensland, and tens of thousands of international travelers use it as a jumping-off point for activities such as scuba diving and snorkeling trips to the Barrier Reef, as well as boating, fishing, parasailing, scenic flights, and rain-forest treks.It's a tough environment, with intense heat and fierce wildlife. Along with wallabies and grey kangaroos in the savannah and tree kangaroos in the rain forest, you'll find stealthy saltwater crocodiles, venomous snakes, and jellyfish so deadly they put the region’s stunning beaches off- limits to swimmers for nearly half the year. Yet despite this formidable setting, Cairns and tropical North Queensland are far from intimidating places. The people are warm and friendly, the sights spectacular, and—at the right time of year—the beachside lounging is world-class.

Darwin is Australia's most colorful, and exotic, capital city. Surrounded on three sides by the turquoise waters of the Timor Sea, the streets are lined with tropical flowers and trees. Warm and dry in winter, hot and steamy in summer, it's a relaxed and casual place, as well as a beguiling blend of tropical frontier outpost and Outback hardiness. Thanks to its close proximity to Southeast Asia and its multicultural population it also seems more like Asia than the rest of Australia. Darwin is a city that has always had to fight for its survival. The seductiveness of contemporary Darwin lifestyles belies a history of failed attempts that date from 1824 when Europeans attempted to establish an enclave in this harsh, unyielding climate. The original 1869 settlement, called Palmerston, was built on a parcel of mangrove wetlands and scrub forest that had changed little in 15 million years. It was not until 1911, after it had already weathered the disastrous cyclones of 1878, 1882, and 1897, that the town was named after the scientist who had visited Australia's shores aboard the Beagle in 1839. During World War II it was bombed more than 60 times, as the harbor full of warships was a prime target for the Japanese war planes. Then, on the night of Christmas Eve 1974, the city was almost completely destroyed by Cyclone Tracy, Australia’s greatest natural disaster. It's a tribute to those who stayed and to those who have come to live here after Tracy that the rebuilt city now thrives as an administrative and commercial center for northern Australia. Old Darwin has been replaced by something of an edifice complex—such buildings as Parliament House and the Supreme Court all seem very grand for such a small city, especially one that prides itself on its casual, outdoor-centric lifestyle. Today Darwin is the best place from which to explore Australia's Top End, with its wonders of Kakadu and the Kimberley region.

Pink Beach earned its name for the way the beach can appear to have a rosy hue in certain lights. The color comes from small flecks of red coral mixed in with the fine white reef sand. With a few trees along the beach for shade, this stretch of coast makes a fine place to relax or enjoy a snorkel or dive in the crystal clear waters. It is possible to spot a striped clown fish nestled among the protective tentacles of its sea anemone host, or to see a grouper lazily swimming by a flamboyant soft coral. The reef here is now protected by law and the maturing corals are a joy to behold.
