Dawesville Channel is a man-made cut connecting the Peel Inlet and Harvey Estuary to the Indian Ocean at Dawesville, roughly 90 km south of Perth. This engineered waterway creates a dynamic mixing zone where estuarine and marine waters meet, offering clear snorkelling conditions on calm days near the channel entrance. The surrounding area is famed for its thrombolite formations (living fossil microbialites) in nearby Lake Clifton, while the channel itself attracts a variety of fish drawn by tidal flows. Nestled between white-sand beaches and coastal bushland, it's a unique spot for snorkellers interested in exploring the interface of ocean and estuary ecosystems.

- Strong tidal currents danger
The channel connects the estuary to the ocean, generating powerful tidal flows through the cut that can sweep swimmers out to sea or into the estuary. Extremely dangerous at peak tidal movement.

High risk: Strong tidal currents
The channel connects the estuary to the ocean, generating powerful tidal flows through the cut that can sweep swimmers out to sea or into the estuary. Extremely dangerous at peak tidal movement.
Moderate risk: Boat traffic
The Dawesville Cut is a busy navigational channel used by fishing boats, recreational vessels, and jet skis transiting between the Peel Inlet and the Indian Ocean.
Moderate risk: Changing water conditions
Mixing ocean swells and estuarine outflow creates turbulent, unpredictable water conditions with sudden changes in visibility and current strength.
Moderate risk: Tidal currents in channel
Strong tidal flows rush through the narrow Dawesville Channel as the estuary drains and fills, creating powerful currents that can sweep snorkellers away from the entrance zone. Most dangerous around peak tidal movement.
Low risk: Stinger jellyfish
Box jellyfish and other stinger species may be present in warmer estuarine and nearshore waters during the summer months (November to April).
