Lose track of time, and yourself, in one of the most magical secret gardens in Australia.

There’s a reason why the children’s novel, The Secret Garden, remains enchanting more than a century beyond its release. To glimpse an unspoiled world, cloaked in flourishing plant life and elusive wildlife that evidently tend to themselves, evokes a timeless curiosity in what lies beneath.

In pursuit of these natural havens during every Aussie adventure, we’ve rounded up our top picks for you to hunt down yourself. From spectacular seasonal blooms to unexpected surprises, the country’s best secret gardens connect you to nature in extraordinary style.

1. Wendy’s Secret Garden, NSW

A totally immersive art gallery, Wendy Whiteley’s Secret Garden on Sydney’s north shore is practically spiritual. One of Australia’s best “hidden" gems, the garden is the scrupulous handwork of Wendy Whiteley, wife of late artist Brett Whiteley, and it flows with every imaginable shade of green.

Dotted through the space, which is set on a steep hill that rolls down to Sydney Harbour, are sculptures and many other endearing artefacts. Once you reach the garden’s centre, you’ll also find chairs and benches to be perched upon as you soak up the wonderment. Bird baths, cherubs, an ancient wheelbarrow and a metal fountain from the late Margaret Olley, another iconic Sydney artist, await amid a manicured mass of palms, shrubs and trees.

What it’s really like to stay on the world’s largest sand island

    Kassia Byrnes Kassia Byrnes
    Exploring the world’s largest sand island starts with the perfect K’gari homebase.

    The morning light is still soft, but it’s already a perfect sunny day. We left our K’gari homebase at Kingfisher Bay Resort with our guide, Peter Meyer, at 9 am to make the most of our time to explore all that the world’s largest sand island holds. The size of K’gari is hard to grasp until you arrive here. This is no sandbar. Stretching 120 kilometres, unique lakes, mangrove systems, rainforest, 75 Miles of beach, historic shipwrecks, small townships and even one of Queensland’s best bakeries are all hidden within its bounds.

    But first, one of the island’s most iconic sights: the pure silica sand and crystal clear waters of Lake McKenzie.

    Laying eyes on it for the first time, I’m finally able to confirm that the photos don’t lie. The sand is pure white, without the merest hint of yellow. The water fades from a light halo of aqua around the edges to a deeper, royal blue, the deeper it gets (not that it’s particularly deep, six metres at most). The surface remains surprisingly undisturbed, like a mirror.

    Arriving with our guide before 10 am means that no one else is around when we get here. Which means we have the pleasure of breaking the smooth surface with our own ripples as we enter. As a self-confessed wimp with chilly water temperatures, my fears are quickly assuaged. Even in the morning, the water stays around 23 degrees – perfect for lazing about all day. But we have more sights to see.

    Exploring K’gari

    This was the Personalised 4WD tour offered by Kingfisher Bay Resort, and my absolute top pick of experiences. Over the course of the day, we had the freedom to create our own bespoke itinerary (plus a provided picnic lunch along the way), with an expert guide who had plenty of stories and local expertise to give context to what we were looking at. From the history of the SS Maheno shipwreck, which survived the First World War only to be washed ashore by a cyclone in 1935, to a detailed description of how an island made of sand could sustain such diverse flora.

    If it’s your first time to K’gari, the Beauty Spots Tour is another great option. Departing daily from Kingfisher Bay Resort (you’ll start to notice a trend, as many of the tours do start and end here), an air-conditioned, 4WD bus takes guests to the island’s most iconic locations, including the best places to swim, like Lake McKenzie and Eli Creek. The latter offers a gentle current, perfect for riding with a blow-up tyre out towards the ocean.

    The next day, for a look at a completely different side of K’gari, I joined one of Kingfisher Bay Resort’s Immersive Ranger-guided tours to kayak through the mangroves of Dundonga Creek. This long, snake-like stretch of creek winds its way inland from the ocean outlet we entered by, at times too narrow for three kayaks to be side-by-side. Small insects buzz from leaf to leaf, while birds call overhead. Occasional bubbles indicate we’ve passed some fish that call this place home.

    If kayaking isn’t for you – or if, like me, you simply want more – other ranger-led experiences include nature walks and a dedicated Junior Eco Ranger Program for kids ages five to 12 (these run every weekend, and daily over the peak December holidays). Just ask for a timetable of upcoming tours when you check in.

    While during whale season, Hervey Bay Whale Watch & Charters operates tours from the hotel’s jetty to get up close to the famous Humpback Highway of Hervey Bay, from 7 November to 31 May, attention turns to the Aqua Oasis Cruise. Departing from the resort every Tuesday, Thursday, Saturday and Sunday for resort guests, adventure along the island’s remote western coast, pointing out wildlife like dolphins, turtles, flying fish and eagles along the way.

    The cruise drops anchor so guests can jump into the water using the boat’s equipment – from SUP boards to inflatable slides and jumping platforms. Then refuel with a provided lunch, of course.

    Unwind at sunset

    As much as days on K’gari can be filled with adventure, to me, the afternoons and evenings there are for unwinding. Sunsets on K’gari are absolutely unbelievable, with Kingfisher Bay on the west side being the best spot to catch the colours.

    The Sunset Bar, located at the start of the resort’s jetty and overlooking the beach, is the ultimate location for sundowners. Let chill beats wash over you as you sip on cool wines, beers and cocktails in a relaxed, friendly vibe. Personally, a cheese board was also absolutely called for. As the sun sinks, the sand, sea and horizon turn a vibrant shade of orange, with the jetty casting a dramatic shadow across the water.

    When the show is over, head back to the hotel for dinner at the Asian-fusion Dune restaurant, or the pub-style Sand + Wood. But if your appetite is still whetted for more lights and colours, the evening isn’t over yet.

    Settle into the Illumina stage for Return to Sky, an immersive light and sound show leading viewers on a captivating journey through K’gari’s stories and landscapes.

    Indulge and disconnect

    Of course, there is a type of traveller who knows that balance is important, day or night. While Kingfisher Bay Resort offers more than one pool for guests to spend all day lounging by (they’ll even serve you food and drinks while you do it), you’ll find me at the Island Day Spa.

    The masseuses could match the magic hands of any big city spa, and I felt the warm welcome as I walked into the light, breezy reception. Choose from a range of botanical facials, beauty treatments and soothing massages using traditional techniques (obviously, I couldn’t go past a relaxing massage). All products used contain organic, native botanical ingredients with nutrient-rich plant extracts to soothe skin and mind. To really indulge, try out one of the packages, couples treatment or even a pre-wedding day offering.

    Getting there

    Getting to K’gari is shockingly easy. Find daily flights into Hervey Bay from Brisbane, Melbourne and Sydney. Kingfisher Bay Resort offers a shuttle bus between the airport, their headquarters in Hervey Bay and the ferry to take you to K’gari.
