13 things you didn’t know about Kangaroo Island

hero media
If you haven’t heard much about this little slice of South Australian paradise by now, check out these fun facts.

It’s only 150 kilometres long, yet Kangaroo Island is home to arguably the densest and most varied menagerie of wildlife in Australia. Its landscape is so diverse you won’t believe that all of this can be crammed onto one island. And it’s also crammed full of some weird and wonderful facts.

1. Kangaroo Island is bigger than some countries

KI is seven times the size of Singapore at 4400km2. At its narrowest point, it’s just 900m wide.

2. One of its parks was founded to combat “brain fag"

Flinders Chase National Park was established in 1919, “as a bit of a sanctuary for those suffering from ‘brain fag’", according to the park’s founding father Samuel Dixon. Brain fag is a type of mental fatigue, in case you were wondering.

3. Kangaroo Island roos aren’t quite the same

The kangaroos on KI are slightly different from the mainland ones. They have longer fur and are darker in colour, having been separated from their mainland family for approximately 10,000 years.

4. Descriptions here are remarkably to the point

The Remarkable Rocks sit on Kirkpatrick Point, named after an 1899 shipwreck survivor. The term is from an original chart that described some “remarkable rocks". Today we know that they are around 500 million years old and shaped by rain, wind and waves.

5. It’s seen plenty of shipwrecks

There have been more than 80 shipwrecks off KI since records began in 1847. The last of its three lighthouses (Cape Borda, Cape du Couedic and Cape Willoughby) was built in 1909 but at least 19 ships have been wrecked since, the latest in 2008.

6. Plants here have an explosive good time

Tate’s grass trees, known as yaccas in SA, grow 0.5 to 2.5mm a year. Until 1997 their red resin was harvested to make a gum that is used in fireworks, explosives and munitions.

7. There is an abundance of produce created here

Whether it’s because of the homegrown wineries or the restaurants with kitchens stacked with Kangaroo Island goods, trust us when we say that eating well on KI is not going to be a problem.

12. KI also has a French name

KI could also be known as I’Île Decrès, as French explorer Boudin published the first map of the island in 1811 – three years before Flinders. For the mainland Indigenous residents, Kangaroo Island is known as Karta Pintingga – or island of the dead.

7 Kimberley experiences that need to be on your bucket list

From thundering waterfalls to ancient Indigenous art, Kimberley’s raw beauty will take your breath away.

Wild, pristine, and shaped by nature, the Kimberley Coast is one of Australia’s most spectacular landscapes. A remote and rugged frontier that remains a bucket list destination for many travellers. Its most breathtaking attractions – including Montgomery Reef, King George Falls and Horizontal Falls – are accessible only by sea or air, making a guided expedition cruise aboard Silversea’s luxury expedition ship, Silver Cloud, the ideal way to explore it.

From its intricate intertidal zones to ancient rock art, extreme tides and rare wildlife found nowhere else in Australia – or the world – this journey offers an unparalleled exploration of one of Earth’s last true wildernesses.

Why Silversea?

Silversea offers a 10-day expedition departing Broome, or an extended 16-day expedition voyage from Indonesia, including landings on the hidden gems of Palopo Sulawesi and Komodo. Accompanied by expert guides and specialists in marine biology, history and geology, guests gain a deeper understanding of the Kimberley’s dramatic landscapes, rich cultural heritage and extraordinary biodiversity.

Silversea offers one of the experiential travel industry’s leading crew-to-guest ratios. Along with all-suite accommodation (80 per cent with private verandah), 24-hour butler service, a swimming pool and four dining options. Silver Cloud also has an experienced crew of multilingual expedition guides and specialists in marine biology, history and geology to enhance your Kimberley Experience.

1. Koolama Bay

​​Before visitors see King George Falls, they hear them – a growing rumble in the distance, steady and foreboding as the Zodiac glides through the gorge, the sound echoing off sheer rock formations. At 80 meters tall, the twin cascades carve through the red cliffs, churning the waters below in a spectacular finale – but Koolama Bay holds secrets beyond its striking scenery.

Named after a ship that beached here following an aerial attack by Japanese bombers in World War II, the bay may seem desolate, yet it teems with life. With Silversea’s expert guides on their 10-day Kimberley itinerary, guests gain a sharper eye for its hidden wonders – rock wallabies darting across the cliffs, crocodiles lurking among dense green mangroves, and high above, the silhouette of a bird of prey circling the sky.

2. Freshwater Cove / Wijingarra Butt Butt

Connect with Country on a wet landing at Freshwater Cove, also known as Wijingarra Butt Butt. Considered one of the most special experiences on both the 16-day and 10-day Kimberley cruises, Silversea guests are welcomed by the traditional Indigenous custodians of the land, painted with traditional ochre, and invited to take part in a smoking ceremony.

Located on the mainland near Montgomery Reef, Wijingarra Butt Butt holds deep cultural significance to the local Indigenous community. Here, rock formations along the shore represent spiritual ancestors, and guests are guided to a nearby rock overhang filled with ancient art, where traditional owners share the stories and meaning behind these sacred paintings.

3. Vansittart Bay (Jar Island)

Modern history, ancient culture and mystery converge in Vansittart Bay, which is also known as Jar Island. Here, the first thing to catch the eye is the dented, silver fuselage of a World War II-era C-53 plane – a striking relic of the past. Yet, the true cultural treasures lie just a short hike away where two distinct styles of Indigenous rock art – Gwion Gwion and Wandjina – can be found.

The Wandjina figures, deeply connected to Indigenous traditions, stand in stark contrast to the enigmatic Gwion Gwion (Bradshaw) paintings, which date back more than 12,000 years. Significantly different in form and style, the two different styles create a striking juxtaposition, offering a rare glimpse into the region’s rich and complex past.

4. Horizontal Falls

Part illusion, part natural phenomenon, the Kimberley’s much-lauded Horizontal Falls aren’t a waterfall, but a tidal and geographic spectacle that visitors have to see to comprehend. Known as Garaanngaddim, the phenomenon occurs when seawater rushes through two narrow gaps- one just twenty metres wide, and the other seven metres in width, between the escarpments of Talbot Bay.

With each tidal shift,  the force of the water creates whirlpools, furious currents and the illusion of a horizontal cascade as thousands of gallons of water are pushed and pulled in through the gap every six hours with relentless movement, making this one of the Kimberley’s most mesmerising natural wonders.

Horizontal Falls are described as "One of the greatest wonders of the natural world". They are formed from a break in-between the McLarty Ranges reaching up to 25m in width. The natural phenomenon is created as seawater builds up faster on one side of the gaps than the other, creating a waterfall up to 5m high on a King tide.

5. Montgomery Reef

As the tide turns in Montgomery Reef, magic happens. With the Kimberley’s legendary tides varying up to ten metres, at low tide the submerged reef almost appears to rise from the depths: exposing up to four metres of the sandstone reef.

The impact is otherworldly: as the water drains, waterfalls cascade on either side of the channel,  turtles left exposed scramble and dive, and fish leap in search of sanctuary in shallow pools. Meanwhile, the dinner bell rings for the migratory seabirds dugongs, reef sharks and dolphins that scavenge and feast in the area.

Using zodiacs, guests cruise through one of the world’s most significant inshore reef systems navigated by experienced guides, exploring the most intricate and fascinating parts of a 300-square-kilometre-wide biodiversity hotspot.

6. Mitchell Falls by Helicopter

Experiencing the Kimberley by sea allows you to feel the power of the tides, but travelling by helicopter reveals the sandstone tapestry of the Kimberley, a landscape geologists believe is over 1.8 billion years old.

One of Silversea’s most popular optional excursions, guests who opt to fly into the interior from the onboard helipad soar up above the rust-coloured landscape of the Mitchell plateau, taking in one of Australia’s most scenic waterfalls: Mitchell Falls, a series of four emerald-coloured pools gently cascades into each other, before plunging down to the river below.

Seeing the landscape from above reveals a landscape weaved and shaped by the power of the freshwater wet season, juxtaposed to the constant lapping of the relentless and powerful tide on the coast.

7. Indigenous Art Caves, Wandjina Art

The Kimberley Region of Western Australia is home to some of the most striking and significant

Indigenous rock art in Australia. Dotted throughout the landscape are caves, cliffs and rock overhangs depicting the striking, ethereal image of Wandjina, the rainmaker spirit and creation being central to many of the Dreamtime stories in this region.

Some of the paintings are regularly repainted by traditional custodians, while others are believed to be over 4,000 years old. Each artwork serves as both a cultural record and a living connection to the past, offering a rare opportunity to engage with the enduring traditions of the Kimberley’s Indigenous communities.
