Nestled just 600 metres off the northern coast of New South Wales ‘Joongarra-Ngarrian‘, also known as Cook Island, stands as a beacon of biodiversity in the vast expanse of the ocean. This aquatic reserve, situated near Fingal Head, is a mesmerising oasis where the vibrant world beneath the waterline comes to life. Join us on a journey through the azure waters surrounding Cook Island, a haven for marine life.
Discovering the Underwater Symphony:
Embarking on a short trip through the Tweed River, you’ll find yourself approaching the glistening waters that embrace Cook Island. Equipped with a mask, snorkel, and fins, you’ll descend into a world of colour and diversity. The ocean, with its ever-changing shades of blue, dances around the island, revealing a kaleidoscope of life beneath the surface.
A Palette of Colours:
As you explore the underwater wonderland, your eyes are treated to a breathtaking display of colours. Fluorescent greens, pinks, purples, and browns adorn the rocks, covered in a tapestry of algae and coral. The aquatic landscape becomes a living canvas, showcasing the beauty of both tropical and temperate fish that gracefully navigate through their vibrant habitat.
Life Finds a Home:
Look closely, and you’ll realise that every inch of Cook Island tells a story of life. The basalt rocks, remnants of the ancient eruptions of ‘Wolumbin’ (Mt Warning), have become a sanctuary for algae, coral, sponges, mollusks, crustaceans, and various invertebrates. The history of the island is etched in these rocks, transformed into a thriving ecosystem over millions of years.
Green Sea Turtles: Ancient Grazers of the Sea:
One of the most enchanting sights at Cook Island is the presence of ancient Green Sea Turtles. Floating on the surface, gazing through your mask and breathing through your snorkel, you’ll witness these majestic creatures gracefully grazing upon the algae-covered basalt rocks. As hatchlings, Green Sea Turtles are opportunistic omnivores, feeding on a variety of plants and animals.
However, as adults, they transition into herbivores, primarily consuming algae, seagrass, and seaweed. Their saw-like beaks expertly scrape these nutritious elements off the rocks, leaving behind a trail eagerly scavenged by small fish. From the boat, every half an hour or so you’ll see turtles breaching the ocean surface with their ornate shells and lifting their heads to the sky for a breath or two before descending again, holding their breath for another half-hour to get back to their business of feeding, resting or maybe even mating.
A Symphony of Life:
Cook Island stands as a testament to the resilience and interconnectedness of marine life. It’s a sanctuary where the past and present coalesce, offering a glimpse into the intricate dance of nature. So, the next time you find yourself on the northern coast of New South Wales, don’t miss the opportunity to immerse yourself in the underwater paradise of Cook Island—a place where the symphony of life plays out beneath the gentle waves.
