There will not be an inquest into the death of a couple snorkelling near Ningaloo Reef, with the Coroner saying there is no evidence to support suggestions they might have been stung by deadly irukandji jellyfish.
The body of Canberra woman Kathreen Ricketson, 41, washed up at Elle's Beach, south of Coral Bay, on May 15 as her two children, a 13-year-old girl and 10-year-old boy, looked on.
After the boy saw Ms Ricketson and his father Rob Shugg, 48, face-down in the water, he raised the alarm. Attempts to resuscitate Ms Ricketson failed and Mr Shugg disappeared before he could be recovered, sparking a massive air, sea and land search.
His body washed up on the same beach nine days later.
The Coroner's registrar at Carnarvon Magistrate's Court said: "The Coroner has made findings that both deceased died by way of drowning. The Coroner determined that death occurred by way of accident. There is no evidence to confirm or deny the involvement of irukandji."
