The wife of a shark attack victim who is yet to be found has described her husband as a "lovely man" and a "wonderful father".
Paul Millachip, 57, is believed to have been taken by a shark while swimming at a beach in North Fremantle in Perth on Saturday morning.
"Rest in peace Paul," his wife said at a news conference on Sunday afternoon.
"He died doing what he enjoyed doing the most, which was exercising."
She thanked authorities for "being extremely thorough" and the witnesses who helped explain what had happened.
Mr Millachip was last seen swimming at Port Beach, as he did regularly, on Saturday morning.
Two teenagers on a boat saw what they believed was a shark attack and called emergency services.
Police said there was an extensive marine search for the father of two, which would be suspended on Sunday afternoon.
The search turned up a pair of goggles believed to belong to Mr Millachip.
"A family is now grieving, a man has lost his life. It's a terribly sad situation," WA Premier Mark McGowan said earlier on Sunday.
All beaches in the area will remain remain closed at least until Monday.
