15-Day Northern Explorer

The port city of Fremantle is a jewel in Western Australia's crown, largely because of its colonial architectural heritage and hippy vibe. Freo (as the locals call it) is a city of largely friendly, interesting, and sometimes eccentric residents supportive of busking, street art, and alfresco dining. Like all great port cities, Freo is cosmopolitan, with mariners from all parts of the world strolling the streets—including thousands of U.S. Navy personnel on rest and recreation throughout the year. It's also a good jumping-off point for a day trip to Rottnest Island, where lovely beaches, rocky coves, and unique wallaby-like inhabitants called quokkas set the scene.Modern Fremantle is a far cry from the barren, sandy plain that greeted the first wave of English settlers back in 1829 at the newly constituted Swan River Colony. Most were city dwellers, and after five months at sea in sailing ships they landed on salt-marsh flats that sorely tested their fortitude. Living in tents with packing cases for chairs, they found no edible crops, and the nearest freshwater was a distant 51 km (32 miles)—and a tortuous trip up the waters of the Swan. As a result they soon moved the settlement upriver to the vicinity of present-day Perth.Fremantle remained the principal port, and many attractive limestone buildings were built to service the port traders. Australia's 1987 defense of the America's Cup—held in waters off Fremantle—triggered a major restoration of the colonial streetscapes. In the leafy suburbs nearly every other house is a restored 19th-century gem.

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.

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.

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.
