Imagine being in the midst of a feeding frenzy, surrounded by some of the most fearsome predators in the ocean. This is the reality for those who venture to Neptune Island, off the coast of South Australia, to witness the congregation of great white sharks.
But why do these sharks flock to this particular spot? It all comes down to the abundance of fur seals, which provide a rich energy source for the sharks and make Neptune Island one of the top spots in the world for diving with great whites.
Between July and October, Neptune Island sees a large gathering of great white sharks, with adolescent seal pups being the main attraction. These pups, inexperienced and vulnerable, are easy prey for the sharks, who use their powerful jaws and razor-sharp teeth to tear through flesh and bone.
For those brave enough to dive with these creatures, the experience is unparalleled, providing a unique opportunity to witness the raw power and beauty of nature up close. In this article, we will explore the reasons behind the congregation of great white sharks at Neptune Island, as well as provide tips and insights from experienced scuba divers who have witnessed this incredible phenomenon firsthand.

Why Sharks Congregate
You already know that great white sharks gather around Neptune Island, but do you know why they do it? It’s all because of the fur seals, which provide a rich energy source for these predators. The adolescent seal pups are the main reason why great white sharks congregate around the Neptune Islands. Here’s a deep dive into shark reproduction.
Between May and October, seal pups venture away from the safety of the islands and become prey for great white sharks. Shark behavior is an important aspect of the ecosystem impact of Neptune Island. When these sharks hunt, they surprise the fur seals from below and often breach the surface in a spectacular way.
The seal pups provide a natural food source for the great white sharks and are rich in protein and blubber. More natural predation events are likely to occur around Neptune Island during the time when more great whites arrive to feast on the inexperienced seal pups. This natural process has a significant impact on the ecosystem, as it helps to regulate the population of the fur seals and maintain the balance of the marine food chain.
