WA’s best-kept secret: An ancient tunnel creek cave

hero media
Discover Western Australia’s oldest cave system.

There are many reasons to visit The Kimberley: The Bungle Bungles, Horizontal Falls and incredible helicopter rides over massive waterfalls, to name a small fraction. But a place that you probably haven’t heard about is Dimalurru (Tunnel Creek).

What is Dimalurru (Tunnel Creek)?

About 350 million years ago, the Dimalurru (Tunnel Creek) was underwater, forming part of an ocean reef system. These days, the water level has dropped, but not before carving a huge 750-metre limestone tunnel that gets up to 20 metres high and 15 metres wide in some parts. It’s Western Australia’s oldest known cave system.

Besides its ancient history and incredible natural beauty, this is also a place of significant Australian history. In 1897, it was used as a hideout by the famous/ infamous (depending on who you ask) Bunuba Indigenous leader and freedom fighter of the time, Jandamarra.

Why explore Dimalurru (Tunnel Creek)?

Dimalurra travels from one side of the Napier Range to the other. And as beautiful as the range is from above, there’s an entirely different type of beauty below.

Wander through large caverns, with beams of sunlight leaking in from the world outside. Large stalactite formations hanging down from the roof add to the drama, as do mini-waterfalls along the tunnel wall. Also, keep an eye out for Indigenous rock art near both entrances of the tunnel.

Along the way, you’re likely to spot many different bat species and even freshwater crocodiles that call this cave home.

How to explore Dimalurru (Tunnel Creek)

Napier Range and Dimalurru reside in the West Kimberley, about 2.5 hours (180 kilometres) east of Derby. Head out yourself and take part in a day of hiking. Be sure to wear comfortable shoes that can get wet, and bring a torch (a real one, your phone torch light won’t cut it) as the tunnel gets pitch black in places.

If you don’t want to go it alone, join day trips from Derby, Fitzroy Crossing and Broome.

And, of course, check the Parks and Wildlife Service website for opening updates.

Exploring an icon: inside the massive upgrade to Broome’s famous Cable Beach

    With unhurried mornings, long, sun-filled afternoons, evenings shaped around sunset, this iconic beach offers an all-day experience (and it’s about to get even better).

    As the sun slowly rises over the languid waves and fine sand of Broome’s Cable Beach, the morning colours shift from rich apricot to pale gold and frosty pearl. Remnants of life reveal themselves in the subtle shadows – crab claw marks, towel impressions, footprints. Life here is unhurried, but don’t be fooled. This town is continually shifting like the desert dunes that surround it.

    And with a $75 million upgrade – offering easier and more inclusive access for people of all abilities – it’s getting even better.

    The addition of comfortable and welcoming spaces has begun (and will continue). This means visitors will be able to spend longer enjoying this beautiful environment, while knowing that the upgrade will create a more environmentally protected setting that preserves the natural character visitors come for. Come sunset, soak it in all the better thanks to the already improved foreshore areas, made for lingering while the light changes. And for the kids, a new splash park and accessible dry playground will make it easy to while away the hours.

    Think you know what a day at this beach is like? Think again.

    Morning colours

    As the sun colours the sky, Cable Beach shows signs of life (and not just the aquatic kind). Locals and visitors alike float in the cool water as it laps the shore, landlubbers explore the coast on foot, runners pace and beachside yoga classes bring quiet movement to the day.

    When the sky is blue and the sun is firmly in position, head down to the well-known Cable Beach House for a long, slow breakfast overlooking the ocean. Think fresh tropical fruit, eggs cooked your way and strong coffee in the warm morning breeze.

    Afternoon adventures

    When you’re ready to explore, carve a path along the Minyirr Park Trail – a gentle 1.5-2km track through coastal bushland with spectacular views of the dunes. Refuel at the nearby Spinifex Brewery for lunch with its low-key, outdoor beer garden. There’s even an outdoor playground if you’re travelling with young humans.

    Walk off your lazy lunch by watching (or joining) one of the beach soccer or volleyball games, or even try Silent Beats Broome – a silent walking disco through the dunes. Or book a spot on the famous camel trains, watching the sun drop below the horizon along the way. They’re a constant reminder of the fascinating history, landscape and cultural mix in this part of the country.

    As the day closes, watch the world-famous Cable Beach sunset from the appropriately named Sunset Grill at Cable Beach Club. This open-air terraced dining spot overlooking the beach is the kind of place where the view takes centre stage.

    While you sip on a lychee, lime & lemonade mocktail or a local beer, enjoy the bustle of life and nature outside as the day comes to an end.

    For dinner, nab a table at the Bali Hai Cafe, where they offer pan-fried crispy barramundi, Abrolhos Island scallops and deep-sea snow crab. When you’re ready for bed, check in to Pinctada Hotel Broome – a lush, tropical resort with palm-dotted gardens and a large, lagoon-style pool to cool off in.

    Beyond the beach

    Beyond the wide, open beach and never-ending sky of Cable Beach, there are many more reasons to visit North West Australia. These are just a few.

    Unmatched experiences

    Engage with the history of the land and its people on an Indigenous cultural tour exploring everything from the local wildlife to the tastes of bush tucker. To understand the importance of pearling to this town, take a tour of Chinatown, or head outside of town to the live pearl harvests at Willie Creek or Cygnet Bay Pearl Farm, one of Australia’s oldest pearl farms.

    Learn why Japanese pearlers were central to Broome’s pearling success and visit the largest Japanese cemetery in Australia, where 900 Japanese pearlers were buried – a testament to the risks and rewards of this dangerous profession.

    And book ahead every spring for when communal tables, freshly cooked local fare and festoon lighting fill the beach for the extremely popular Long Table Dinner on Cable Beach. It’s a highlight of the Shinju Matsuri Festival, along with the Floating Lanterns Matsuri, where you can personalise a lantern and gently release it into the sea to honour those you love.

    Dining discoveries

    Further your culinary adventure at the laid-back Sunday Sesh at Matso’s Broome Brewery. Chow down on smoked crocodile or Aussie barramundi while kicking back to a local DJ as the heat of the day fades.

    For more tunes, the beautiful outdoor Bay Club at the Mangrove Hotel is a great choice for dinner with live music, DJs or an event that stretches on into the early hours. Still hungry? Pop by Johnny Sausage for Italian-influenced meals paired with impeccable wines.

    Natural beauties

    Avoid the crowds and head to Town Beach for a quieter vantage point to see the phenomenal Staircase to the Moon – a natural illusion where the rising full moon is reflected on the tidal flats, creating a shimmering ‘staircase’ stretching up to the sky.

    Just south of Cable Beach are the deep red cliffs and dramatic ocean views of Gantheaume Point, where 130-million-year-old dinosaur footprints can be seen, revealed at low tide. Or head to Roebuck Bay to visit the internationally significant wetlands, where vast tidal flats are home to shorebirds and coastal fauna.

    Between October and March, watch turtles nesting and hatchlings emerge from the sand. You’ll be holding your breath as they make their way down to the shoreline, ready to start their life in one of Australia’s most beautiful landscapes.
