False Bay lies between Nurrea Banga Nassi and Maipura Point, about 20 miles NE, at the entrance of the Maipura River.
Depths in the bay decrease gradually toward the shore over a bottom of olive-green mud, in the S part, to a bottom of sand and mud, in the N part.
The shore on the W of the bay consists of moderately-high sand hills.
Caution.—The Gahiramatha Marine Wildlife Sanctuary, best seen on the chart, lies roughly between the 10m and 20m contours in False Bay. Fishing, trawling, or any other activity harmful to marine life within this area is prohibited.
