From far-flung hideaways to see-and-be-seen hot spots, these six beaches are the best Australia has to offer.

For Explorers: Cable Beach, Broome

The Scene: Adventurous types make the 2 1/2-hour flight from Perth to Western Australia's exotic pearling port for a frontier-town atmosphere and a 13-mile sweep of white sand.

T+L Tip: Hole up at the luxe Cable Beach Club (61-8/9192-0400; doubles from $297) and arrange to join a 32-camel sunset caravan along the beach with Ships of the Desert (61-419/954-022; 30-minute tours from $31 per person).

For Serenity Seekers: Four Mile Beach, Port Douglas

The Scene: How to improve on a pristine arc of shoreline along the Great Barrier Reef? Have it all to yourself. This is Queensland's discreet bolt-hole for the stealth-wealth set.

T+L Tip: Check in to Peppers Beach Club (61-7/4087-1000; doubles from $339), where the white-on-white interiors and a huge pool are refreshing on steamy summer days.

For Sybarites: Watego’s Beach, Byron Bay

The Scene: A former whaling town just a two-hour drive from Brisbane, Byron Bay has evolved into a hip beach getaway thanks to an influx of fashion-industry players who love the calm waves and hard-packed sand ideal for yoga sessions.

T+L Tip: Book one of 92 suites at the Byron at Byron (doubles from $423), set in a tranquil rain forest.

For Scenesters: Bondi Beach, Sydney

The Scene: Just 20 minutes from downtown, this half-mile crescent is the fulcrum around which Sydney—with its enviable work-life ratio—revolves.

T+L Tip: Relax in the seawater pool at Bondi Icebergs (61-2/9130-3120), the venerable swimming club on a cliff overlooking the beach.

For Nature Lovers: Wineglass Bay, Tasmania

The Scene: Go in search of Tasmanian devils and wallabies in their natural habitat at this flawless beach with the Hazards Mountains beyond.

T+L Tip: Unpack at the bold Saffire Freycinet (61-3/6256-7888; doubles from $1,927, including some meals, drinks, and activities), where athletic guides will lead you on a two-hour hike to the bay.

For Surf Bums: Bells Beach, Torquay

The Scene: Expert surfers ride the ocean swells against a dramatic backdrop of craggy cliffs. Ogle the stars during the annual Rip Curl Pro each Easter, or learn from the pros at Torquay Surf Academy (lessons from $121).

T+L Tip: Two hours from Melbourne, the beach is an easy day trip along the spectacular Great Ocean Road. In winter, look out for southern right whales.

The Byron at Byron Resort & Spa

About 75 minutes by air from Sydney, Byron Bay has long been known for its pristine sands and stunning headlands. Set within a 45-acre rain forest, Byron at Byron Resort & Spa was designed by local architect Ed Haysom to blend into the natural canopy. The open plan of the main building flows between indoors and out: wide, covered verandas are furnished with cane lounges and slow-turning ceiling fans. The alfresco restaurant serves mod Oz delicacies with a refined twist. Take a 10-minute tour through the rain forest to the unspoiled Tallow Beach, or just sit back at Byron's infinity pool and poolside sauna and soak in the natural setting.

Saffire Freycinet

A holiday in Tasmania may feel like a trip to the end of the earth. A reward for the long journey? The Saffire Freycinet, Tasmania's first world-class retreat. Spread across 11 lush acres, it is a reimagination of a beachfront shack, with an aesthetic that takes full advantage of the area's natural beauty. Floor-to-ceiling windows overlook the craggy Hazards mountain range, while light-filled living rooms face Great Oyster Bay. Most indulgent touch: each guest is given a complimentary treatment at the 1,600-square-foot spa.
