It is created by the enormous variation in tides - which are as much as 10 metres driven by the massive Montgomery Reef located 30 miles out to sea from the bay. The water level rising, or falling, in Talbot Bay (due to the tide) causes a major height difference with the water level in the inlet on the other side of the Falls. The velocity and mass of water involved in this twice daily event make it one of the largest tidal changes in the world.
Talbot Bay is almost Australia's last frontier, few people have ever seen this spectacular event. There is no car access.
