The bay was named in May 1801 by French explorer Nicolas Baudin; Baudin named the bay after his ship, Géographe. The bay is a wide curve of coastline extending from Cape Naturaliste past the towns of Dunsborough and Busselton, ending near the city of Bunbury. The bay is protected from the rough seas of the Indian Ocean by Cape Naturaliste (named after Naturaliste), which makes it a popular destination for recreational boaters. The bay is extremely shallow, limiting the entrance of large ships. To alleviate the problem the two-kilometre-long Busselton Jetty, the longest in the southern hemisphere, was built.
