The body of a 52-year-old woman has been recovered in Perth's south, taking the toll from a boating accident to two.
Police recovered the body on Sunday night near Creery Island in the Mandurah Estuary.
The family of the woman - identified by media outlets as Kylie Bazzo, the mother of West Coast Eagles AFL player Rhett Bazzo - has been notified as the investigation into the cause of the crash continues.
Emergency services were called to the estuary about 10pm on Saturday after a boat with four people on board struck a red post marker.
A 54-year-old woman was recovered from the water but could not be revived and died at the scene.
A 47-year-old man, believed to be the boat's driver, was taken to hospital with serious injuries while a 54-year-old man was uninjured.
Emergency services continued to search for the missing 52-year-old woman on Sunday, finding her body about 7pm.
Assistant Superintendent Peter Morrissey said speed would be investigated as a factor in the crash but that it was too early to consider criminal charges.
