While it might not be as famous as Rottnest Island, Carnac Island holds a unique charm all its own, especially for nature lovers and history enthusiasts. Known for its incredible wildlife, including the playful Australian sea lions that call it home during certain seasons, Carnac Island offers an unforgettable experience for visitors. Whether you’re intrigued by its historical roots or keen on observing the local fauna, Carnac Island is a must-visit destination.
The History of Carnac Island
Carnac Island, originally named Île Lévilian by French explorers in 1803, was later renamed after John Rivett Carnac, a Royal Navy officer who surveyed the island. The island’s history, however, goes beyond its European naming.
For thousands of years, the island was connected to the mainland, part of the now-submerged coastal plains. When sea levels rose, it became isolated, with a fascinating human and natural history.
Today, Carnac Island is a protected A-class nature reserve, meaning its primary purpose is to conserve its natural environment, making it a sanctuary for wildlife.
Carnac Island’s Special Wildlife
While the island’s human history is rich, it’s the wildlife that makes Carnac truly special. This tiny island, spanning just 19 hectares, is teeming with life, both on land and in the surrounding waters.
Australian Sea Lions
The star attraction of Carnac Island is undoubtedly the Australian sea lions. Listed as a vulnerable species, these sea lions are unique to Australian waters, and Carnac is one of the few places where you can observe them in the wild. During the summer months, sea lions use Carnac as a “haul-out” site, a place to rest, sunbathe, and socialize between hunting trips. Watching these playful animals frolic in the water or bask on the shore is a sight to behold, especially given their curious and interactive nature.
However, it’s important to note that while the sea lions are fascinating to observe, they are wild animals and can be aggressive if disturbed. Visitors are advised to keep a safe distance and respect the guidelines set by conservation authorities.
Other Wildlife
While the sea lions are the main draw, they’re far from the only wildlife on the island. Carnac Island is also home to large populations of seabirds. The island’s rocky shores and native vegetation provide ideal nesting grounds for several bird species, including:
- Pied Cormorants
- Silver Gulls
- Caspian Terns
Carnac’s ecosystem also supports the dugite, a non-venomous snake species that’s native to the island. These snakes have thrived on Carnac due to the lack of predators, and though they are common, they tend to stay out of the way of visitors.
The surrounding waters of Carnac Island are equally vibrant, with diverse marine life such as dolphins, fish species, and even the occasional stingray. The island’s shallow reefs are also perfect for snorkelling, offering a glimpse of the underwater world that teems with colourful fish and marine vegetation.
Why Carnac Island Is So Special for Wildlife
Carnac Island’s significance lies in its status as a sanctuary for wildlife. The isolation from the mainland has allowed many species to thrive in an environment free from the pressures of development. The island is off-limits to permanent human activity, which helps preserve the natural balance. Here’s why Carnac is particularly vital for wildlife:
Protection for Vulnerable Species
As a protected nature reserve, Carnac Island serves as a safe haven for species like the Australian sea lion, which faces various threats in other parts of the world due to habitat loss and fishing industry interactions. Carnac provides these sea lions with a critical resting spot where they can recover between hunting excursions.
Unique Ecosystems
The island’s small size belies its ecological diversity. From rocky shores and limestone cliffs to native shrubs and shallow reefs, Carnac Island boasts a range of habitats that support a wide variety of species. This biodiversity makes the island an important ecological hotspot for both land and marine wildlife.
Birdwatcher’s Paradise
For birdwatchers, Carnac Island is a treasure trove of species. The island’s seclusion and abundant food sources make it a key site for seabird nesting, and visitors can often spot bird colonies during breeding seasons. The unspoiled nature of the island’s environment makes it an ideal place to observe birds in their natural habitat without the distractions of urban development.
Visiting Carnac Island: What You Need to Know
If you’re planning to visit Carnac Island, there are a few important things to consider. Since the island is a protected reserve, there are restrictions on what you can do to ensure the wildlife is not disturbed.
- Respect Wildlife: Whether you’re there for the sea lions or the birds, it’s essential to observe all wildlife from a safe distance. Australian sea lions, while friendly, are still wild animals and can become dangerous if approached too closely.
- Access: The only way to reach Carnac Island is by boat. We offer private tours from Fremantle, that include snorkelling and wildlife-watching activities, which allow you to experience both the land and marine life of the island.
- Leave No Trace: As with any nature reserve, visitors should practice the “Leave No Trace” principle. This means taking all your rubbish with you and not interfering with the environment or the animals.
