TWO young children have been seriously injured and a man cut from the wreckage of a van that hit a Stobie pole at Oakden. The van left Fosters Rd near the intersection of Redward Ave and hit the pole shortly after 11am. Emergency crews took almost an hour to extricate the 43-year-old driver, who is believed to have suffered serious injuries.

A car has driven into a pool at Blakeview. Picture: Channel 9 News Ms Curtis, who has been a St John volunteer for 33 years, said it was "very lucky" she happened to be there at the time of the accident. Another witness, who did not want to be named, said he believed the vehicle had veered on to the other side of the road before hitting the Stobie pole. At Blakeview, a resident narrowly escaped injury when a car smashed through a fence of the Heysen Ct property and landed in their pool. The man dived into the pool and dragged the female P-plate driver to safety. She was taken to Lyell McEwin Hospital in a stable condition. On Christmas Day, an elderly woman sustained critical injuries in a head-on crash on the Mt Compass to Goolwa Rd at Currency Creek. The 74-year-old Middleton woman was rushed to the Flinders Medical Centre while the male driver and three passengers in the other car were also taken to hospital with non life-threatening injuries. Police are also searching for a driver who left a woman injured on the roadside in a hit-run incident at Albert Park on Christmas night. She was taken to the Royal Adelaide Hospital with cuts and bruises and police are appealing for any witnesses to the crash. The national Christmas holiday road toll stands at eight.
