Police say the apparent deaths of two people while swimming on a remote beach in Western Australia remains a mystery.
The body of Kathreen Ricketson, 41, was found washed up on a beach near Coral Bay on Wednesday.
Her partner Robert Shugg, 48, is missing presumed drowned.
The couple lived in Canberra and were on a trip around Australia with their two children.
The children have flown to Victoria to stay with their uncle in Melbourne while a search for their father continues.
Police say there are no visible signs of injury on Ms Ricketson and it is difficult to understand how two people could get into trouble in such a non-threatening part of the coast.
