Point Labatt is one of the strongest reasons to base yourself in Streaky Bay rather than just pass through. From a clifftop viewing platform you look down onto a colony of Australian sea lions, often with pups and adults spread across the rock shelf and beach.
Bring binoculars or a long lens. The height keeps visitors out of the colony, which is exactly why the experience works: you watch the animals on their own terms, with the Southern Ocean moving behind them.
