Falcon Bay is a small, reef-fringed bay at Falcon, a southern suburb of Mandurah just north of the Dawesville Cut. A local snorkelling guide describes it as a lesser-known spot with tranquil water, few crowds, abundant marine life and excellent visibility.

Like the rest of the Mandurah coast, the reef is weathered limestone with ledges, pools and gutters covered in algae. Expect wrasse, buffalo bream, sweep, herring cale and small reef fish, along with sea stars, crabs and octopus in the crevices. It is primarily a snorkelling site; no dive-specific survey or depth information was found.

The bay's advantage is quiet water close to the beach, which suits families and snorkellers who want to avoid busier spots. Divers looking for more structure will find it at Blue Bay and Roberts Point in Halls Head, or offshore on the Murray Reefs.

Published information is limited to general snorkelling guides, so this record gives location and general conditions rather than site detail. Check conditions on arrival and stay inside the reef unless the sea is calm. The area is part of the Peel coastal strip, where strong afternoon sea breezes are routine in summer, so plan an early swim.

For anyone basing themselves in Mandurah, Falcon Bay works as a quiet alternative to Blue Bay when that site is busy. Bring a float and a dive flag if swimming outside the bay, as boats use the coastal waters, and wear a wetsuit: water temperatures range from about 17 °C in winter to 22–23 °C in late summer. The Dawesville Cut, a few minutes south, has a boat ramp for anyone wanting to reach the offshore Mandurah Artificial Reef or the Murray Reefs.

From Mandurah drive south along Old Coast Road to Falcon and turn west towards the coast at Falcon Bay; the bay is a few minutes north of the Dawesville Cut. Park at the beach car park and walk down to the sand. Enter from the beach and swim out to the reef.

The site is about 15 minutes from central Mandurah and just over an hour from Perth.

The reef-fringed bay offers some shelter, but westerly swell and the strong summer south-westerly sea breeze reduce visibility and make the reef edges surgy. Snorkel on calm mornings with easterly winds, after several days of low swell. North-westerly winds ahead of winter fronts close it, and runoff after heavy rain reduces visibility, so late summer and autumn are the most reliable months.

Enter from the beach and snorkel or dive along the inshore reef, staying inside the bay unless conditions are calm.
