Sometimes, size does matter. That's true in the case of Ninety Mile Beach, which is actually 94 miles — or 151 kilometres — long, making it one of the longest beaches in the world. It runs along the state's northeastern coastline, parallel to Gippsland Lakes. 

Some beaches are epic, not only for themselves, but for what surrounds them. Take Red Rock, 30 minutes' drive north of Coffs Harbour. The beach takes its name from its stunning headland, a 20-metre-high formation of 300-million-year-old jasper.

Whitehaven Beach was famous for its looks even before Instagram existed. Located on Whitsunday Island, this seven-kilometre-long wonder is known for its sand, which, made of silica, is among the whitest, brightest and purest on the planet.

Cape Tribulation in Queensland's Far North is where two Heritage-listed wildernesses — the Great Barrier Reef and the Daintree Rainforest — come together. Cape Tribulation Beach is the first one north of the cape, around two hours' drive north of Port Douglas.

This breathtaking stretch of sand forms the southwestern border of Coorong National Park, on South Australia's southeast coast. It runs for around 220 kilometres and is considered the longest beach in Australia. 

Another beach that's legendary for its awesome size is 75 Mile Beach on K'gari. This sandy behemoth forms most of the east coast of the island — which is the world's biggest sand island — and lies just off the coast, around six hours' drive north of Brisbane. 

Like Queensland's Whitehaven Beach, Tasmania's Wineglass Bay is known all over the world for its good looks. As you've no doubt guessed, the bay gets its name from its smooth curves, which resemble a wine glass.

Cable Beach, on the edge of Broome, is best known for its camel rides. Every evening, the humped beasts traipse along the shoreline, delivering tourists to some of the most beautiful sunsets in Australia, if not the world. 

Add a bit of island hopping to your beachy bucket list chasing with a quick getaway to the Cocos (Keeling) Islands. These magical wonderlands of coral are in the middle of the Indian Ocean and are considered an Australian territory.

One of the best things about Western Australia's many beaches is that they come with sunsets. And, on Eighty Mile Beach — which sprawls between Port Hedland and Broome — you get 220 kilometres of them.
