Eagle Rock Marine Sanctuary

Eagle Rock Marine Sanctuary is a protected marine area located at Aireys Inlet along Victoria’s Surf Coast. It spans about 17.9 hectares and extends roughly 300 metres offshore from the high‑water mark around the base of Split Point cliff between Castle Rock and Sentinel Rock.

The sanctuary incorporates the dramatic offshore volcanic stack known as Eagle Rock, and nearby Table Rock.

The geology of the area includes basalt and sandstone platforms, leading to a high‑energy coastline with unique marine habitats.

If you’re looking for a striking marine and coastal experience close to the Great Ocean Road, Eagle Rock Marine Sanctuary offers the blend of awe‑inspiring geology, rich underwater habitats (even if challenging), and scenic accessibility. It’s an ideal stop for nature lovers, snorkellers/divers with experience, and anyone wanting to witness wild coastal beauty in a protected setting.

What Makes It Special

The intertidal platforms are rich in algae species with about 25 species recorded.

The iconic brown seaweed Hormosira banksii (commonly known as “Neptune’s Necklace”) forms dense bands on the intertidal rock platforms.

Divers marine life reef fish such as wrasse, sea‑sweep; sharks such as the harmless Port Jackson Shark; stingrays and other invertebrates inhabit deeper reef and rock‑pool areas.

The coastline is exposed and dynamic — strong surf, high wave energy, making the scenes dramatic.

Things to do

Rock‑pool & Intertidal Exploration

At low tide the sandstone and basalt platforms reveal rich rock‑pool ecosystems. Expect to see decorator crabs, chitons, seaweed forms, and small reef creatures.

Snorkelling & Diving

On calm days and when conditions are favourable, the offshore reef and kelp‑fringed areas around Eagle Rock and Table Rock offer snorkelling and dive opportunities. However, because the coastline is exposed, conditions can be challenging and suitable only for more experienced enthusiasts.

Scenic Viewing & Walks

From Split Point Lightstation and the surrounding headland you can enjoy striking coastal vistas, the volcanic stack of Eagle Rock offshore, and dramatic wave action on the reef platforms. Good for photography and nature appreciation.

Plan Your Visit

Getting there: The sanctuary is based around Aireys Inlet. Use the car park at Split Point Lightstation then take stairs down to the beach/rock‑platform area or approach from the nearby creek mouth.

Staying local: Book accommodation and campsites early in peak season.

Stay safe: The site is exposed to strong wind, swell and wave energy. Snorkelling or diving is subject to sea state; rock platforms can be slippery and waves unpredictable.

Wear shoes with good grip when walking rock platforms. Beware of cliff edges, large waves, and slippery surfaces.

Restrictions:

As a marine sanctuary, activities such as fishing, taking or disturbing marine life are prohibited. Check the latest boundary maps and regulations.

Respecting Country: As the land and sea are on Wadawurrung Country, visitors are encouraged to respect cultural heritage and follow park signage and guidance.
