A man missing from an upturned tinny on the Murray, the Federal Minister's tough warning to Holden and more wild weather lashes the state. AN Adelaide man is missing, feared drowned tonight, after his aluminium tinnie boat capsized in wild weather during a camping trip on the River Murray. The man and his friend, who have not been named, hit treacherous conditions near Heading Cliffs, in the Murtho Forest north of Paringa, in the Riverland, just before midday. Authorities suggested the men, who had been travelling between Mildura and Adelaide, were not "prepared" for the wild weather. Just one of the men was wearing a life jacket on the river and police admittedsaid conditions were among the worst seen the area in recent times. Authorities are searching for the body of the Blakeview man, aged in his 30s, who witnesses said did not surface after the boat overturned. Emergency service workers and police prepare to search for a man missing in the River Murray near Paringa.

Gale force winds and choppy conditions were hampering search efforts, which were continuing late last night. The search, involving SA Police Water Operations and State Emergency Service volunteers, is expected to resume at first light this morning. The missing man's friend, 43, from Rostrevor, was able to swim to shore and was taken to the Renmark and Paringa District Hospital. He was treated for hypothermia and discharged this afternoon. Murray Mallee Local Service Area Inspector Kylie Walsh admitted there was little hope of finding the missing man alive. "Given the conditions and the fact that we know that as soon as he went into the water he basically disappeared from sight We are treating it as a recovery operation at this stage," she said. Insp Walsh said the men were making their way down the river from Mildura towards Adelaide. One witness, who gave his name as Kez, said, "there was just police and SES everywhere. It's a tragedy. It would have been the wrong conditions for boating. Another camper, who did not give his name, said he believed he came across the men on the river, near Lake Cullularaine in Victoria, earlier in the week. "Things like this just shouldn't happen." he said. The surviving man actually managed to grab a life jacket and put it around his neck, which probably saved his life, but the other man didn't have a life jacket on and wasn't able to access one when he went into the water. The stretch of water where the tinnie capsized is long and strong westerly winds were whirling straight down it. "I wouldn't say it's a surprise to see people on the river but I would say given the conditions and given that this weather may have come up very suddenly upon them, they certainly didn't seem prepared for it," Insp Walsh said. It's the most choppy and swirly I've ever seen the river. They were dropped off at Mildura sometime in the last couple of days and were making their way back to Adelaide. They had camping gear in the boat with them.
