Great Australian Bight Marine Park

Stretching along the dramatic southern coast of Australia, the Great Australian Bight Marine Park is a remote and wild sanctuary where the Nullarbor Plain meets the Southern Ocean. Here, towering limestone cliffs plunge into turquoise waters, creating one of the most spectacular whale-watching arenas on Earth. This is a place of raw, untamed beauty—expect roaring surf, endless horizons, and a profound sense of isolation that defines the Australian outback meeting the sea.

Highlights & What to See

• Whale watching at the Head of Bight: Between June and October, southern right whales migrate here to calve. From the boardwalks, you can watch mothers and calves mere metres from the cliffs—an unforgettable wildlife encounter.
• The Bunda Cliffs: Stretching for nearly 200 km, these sheer limestone cliffs are among the longest uninterrupted sea cliffs in the world. Stop at lookout points to feel the immense scale and watch for seabirds and dolphins below.
• Nullarbor National Park: Adjacent to the marine park, this arid landscape offers stark desert beauty, cave systems, and the chance to spot kangaroos and emus against a backdrop of endless blue sky.
• Fishing and snorkelling: The park’s protected waters are rich with marine life. Try your luck for Australian salmon or explore the rocky reefs for colourful fish and crayfish (check local regulations).
• Stargazing: With zero light pollution, the night sky here is phenomenal. The Milky Way stretches from horizon to horizon, and you may see the Southern Cross and Magellanic Clouds.

Suggested Time to Spend

Plan at least a full day to properly experience the Great Australian Bight Marine Park. Most travellers visit as a stopover on the epic Eyre Highway crossing, arriving in the afternoon and staying until the next morning. If you’re keen on whale watching (June–October), arrive early and spend several hours at the Head of Bight viewing platform. For a deeper experience, allow two days—one for the marine park and one to explore the Nullarbor’s caves and desert trails. Camping is limited, so book ahead or plan to stay at the nearby Nullarbor Roadhouse.

Nearby Areas Worth Combining

• Eucla: A tiny settlement on the WA/SA border with a historic telegraph station and sand dunes that meet the ocean.
