20 hidden natural wonders you’ve probably never heard of

The hidden natural wonders that are wowing visitors, without the crowds.

Australia is home to some of the most iconic natural landmarks on Earth – think Uluṟu, the Great Barrier Reef and Wineglass Bay. But a new study has uncovered 20 jaw-dropping Aussie destinations that deserve just as much attention – and yet most people have never heard of them.

The research by Mitsubishi Motors Australia analysed over 50,000 Australian locations using data from TripAdvisor, Google and SEO platforms. The goal? To uncover places with exceptional visitor ratings but minimal online searches – aka, Australia’s best-kept secrets. From sacred sites in the Northern Territory to lava tubes in Queensland, these are the hidden spots that offer big wow factor without big crowds.

1. Gunlom Falls, NT

This legendary Top End icon has finally reopened after a six-year closure – and it’s as jaw-dropping as ever. Located within World Heritage–listed Kakadu National Park, the steep but rewarding climb to natural infinity pool Gunlom Falls reveals panoramic views over the escarpment, while the lower pool is equally magical. It’s a sacred site to the Mirarr Traditional Owners, so visitors are asked to tread respectfully and follow all signage.

2. Mount Coot-tha Summit Lookout, Qld

A Brisbane local favourite that deserves wider acclaim, the Mount Coot-tha Summit Lookout serves up sweeping vistas over the city skyline to Moreton Bay. Just 15 minutes from the CBD, it’s the perfect place to watch the sunrise or soak in golden hour with a coffee from the summit cafe. The surrounding forest trails and Botanic Gardens make it one of Queensland’s most accessible escapes.

3. 75 Mile Beach, K’gari, Qld

A beach that doubles as a national highway and a landing strip? That’s 75 Mile Beach on K’gari, the world’s largest sand island. Stretching along the island’s eastern coast, technicolour sand cliffs, crystal-clear creeks like Eli Creek, and natural rock pools such as the Champagne Pools flank this wild and windswept stretch of sand. Four-wheel-drive adventurers will relish the freedom of the open sand, but it’s the untouched beauty that leaves the biggest impression.

4. St Columba Falls, Tas

Hidden deep in Tasmania’s north-east near the town of Pyengana, St Columba Falls is one of the state’s tallest permanent waterfalls, plunging more than 90 metres through a forest of tree ferns, sassafras and myrtle. The short rainforest walk to the falls is atmospheric, and it’s not uncommon to spot platypuses in the river below. Few make the detour, but those who do are richly rewarded.

5. Grassy Hill Lookout, Qld

Cooktown’s most panoramic vantage point, Grassy Hill, is steeped in both natural beauty and complex history. In 1770, it was from this hill that Captain Cook climbed to chart a safe passage for the Endeavour after damaging the ship on the Great Barrier Reef. Today, the lookout offers panoramic views over the Coral Sea and Endeavour River, and serves as a reminder of the need to reflect on both the natural and cultural significance of place. The sunsets are particularly memorable, painting the landscape in warm hues of gold and orange.

And the rest of the hidden gems are…

How many have you ticked off?

A humble trawler turned Hamptons-style dreamboat

It’s a crisp, calm winter’s day, and the sun is pouring down upon Valerie, a restored Huon pine workhorse that was first launched in January 1980. In a previous life she trawled the turbulent Bass Strait. These days she takes jaunts into Port Phillip Bay under the helm of Lance Wiffen, a fourth-generation Bellarine farmer, and the owner of Portarlington Mussel Tours . While Lance has been involved in the fishing industry for 30-plus years, the company’s tour boat only debuted in 2023.

See how these plump and juicy bivalves are sustainably cultivated.

It took more than three years to transform the former shark trawler into a dreamy, Hamptons-esque vessel, with little expense spared. Think muted green suede banquettes, white-washed walls, Breton-striped bench cushions, hardwood tables, bouquets of homegrown dahlias, and woollen blankets sourced from Waverley Mills, Australia’s oldest working textile mill. It’s intimate, too, welcoming 12 guests at most. And yet there’s nothing pretentious about the experience – just warm, down-to-earth Aussie hospitality.

As we cruise out, we crack open a bottle of local bubbles and nibble on the most beautifully curated cheese platter, adorned with seashells and grey saltbush picked from the water’s edge that very morning. Australasian gannets soar overhead, and I’m told it’s not uncommon for guests to spot the odd seal, pod of dolphins, or even the occasional little penguin.

The sustainable secret behind Victoria’s best mussels

Blue mussels sourced just off Portarlington.

Connie and Lance both extol the virtues of mussels. They’re delicious. A lean source of protein and packed with omega-3 fatty acids, vitamin B12, iron, selenium, and zinc. They’re cooked in a flash (Connie steams our fresh harvest with cider and onion jam). And they’re also widely regarded as one of the most sustainable foods in the world.

“Aquaculture is [often] seen as destructive, so a lot of our guests are really surprised about how environmentally friendly and sustainable our industry is,” Lance says. “[Our mussels] would filter 1.4 billion litres of water a day,” he adds, explaining how mussels remove excess nitrogen and phosphorus from the water. “And through biomineralisation, we lock carbon into mussel shells.”

Mussels are a sustainable food.

Despite their glowing list of accolades, these molluscs have long been seen as the oysters’ poorer cousins. “It was a really slow start,” explains Lance, who says that in the early days of his career, “you could not sell mussels in Victoria”.

But word has slowly caught on. Chefs as globally acclaimed as Attica’s Ben Shewry and even René Redzepi of Noma, Denmark, have travelled to these very waters just to try the shellfish at the source, sharing only the highest praise, and using Lance’s mussels in their restaurants.

According to Lance there’s one obvious reason why the cool depths of Portarlington outshine other locations for mussel farming. “The water quality is second to none,” he says, noting how other regions are frequently rocked by harvest closures due to poor water quality. “We grow, without a doubt, some of the best shellfish in the world.” And with Lance’s bold claims backed up by some of the industry’s greatest names, perhaps it won’t be much longer until more Aussies uncover the appeal of Portarlington’s mussels.
