The club appealed for help on Facebook in its search to find Daphne. Anyone who had seen the giant rubber duckie mascot, and could help with her safe return, would be offered a small reward, the Cockburn Masters Swimming Club wrote.

But on Monday, Mr. Marr confirmed that Daphne was no longer missing and had been rescued out at sea. He said he had made contact with her rescuer, and after a scheduled meeting with him on Wednesday, hoped to get Daphne back to where he said she belonged: at home on Coogee Beach, in Perth, in Western Australia.

Her rescue came after Daphne’s fate made headlines around the world and the rounds on social media.

At one point, she was rumored to have been seen 400 kilometers, or about 250 miles, from where she took off at Coogee Beach.

He said Daphne was found by a fisherman 30 to 40 kilometers, or 20 some-odd miles, west of Rottnest Island, just off the coast of the city of Perth.

“Apparently she’s in fairly good condition,” Mr. Marr said of “Daph,” adding that the fisherman “seems like a reasonable bloke.”
