Divers retrieve $110k Porsche from bottom of Berowra Creek Porsche fished from Berowra Creek. The Porsche after it was retrieved from Berowra Creek. A SILVER Porsche Boxter spent more than a week at the bottom of a creek after it rolled down a bank and into the water. The car had rolled under the boomgate on the eastern side of Berowra Waters at 10.30pm on November 7. The ferry was on the other side of the creek at the time and the Porsche's owner chased his car, which has a starting price of $110,000, but couldn't stop it. Commercial diver Nathan Sherwood led the five-hour salvage operation on Monday in atrocious conditions, eventually using a barge to carry the porsche to the western-side boat ramp. "We used depth sounders that pick up all sorts of things on the bottom and once we found it, me and another diver went down there," Mr Sherwood said. It was in about eight metres of murky water and we found it on its roof. We had to rig it up to a crane on a barge so we could get it to the surface, then re-rig it so it was wheels down and we could put it on the ramp. It was a half-day operation in the pouring rain. The car was a write-off. "It came up looking pretty shiny, but it had been in that much mud," Mr Sherwood said. I felt pretty sorry for the owner, the poor guy went through hell. After we got the car up, we went back down there to look for his valuables, but because the car had been upside down and we'd flipped it they could've got caught in the current again and ended up anywhere. Sharyn Gallaway was at Berowra Waters when the car was pulled from the deep. "It looked in pretty good nick, considering where it had been," she said. It actually sat there in the carpark until this morning. It was a pretty expensive swimming lesson, that's for sure.
