A Canberra teen has survived seven days in bushland west of Canberra, after her car rolled down an embankment, by drinking water from a nearby creek.  The crashed car of Kathleen Bautista was found by police yesterday near Cotter Reserve, shortly before officers located the 19-year-old on a nearby hill. She had been reported missing last Saturday.  Her Hyundai i30 had fallen 15 metres down an embankment and flipped on its roof.  Ms Bautista's car wreck at the bottom of the embankment.

Detective Sergeant John Giles said her story was a “miracle”.  “It was a great moment… it’s one of those moments I think you’ll never forget,” Det. Sgt. Giles told The TODAY Show.  Search and rescue teams have found Canberra teenager Kathleen Bautista alive.

Sgt. Giles said Ms Bautista’s survival had defied the odds - particularly the car crash.  “Six days is a long time for a young girl… injured and less than 49kgs, wringing wet, to sustain herself in the middle of nowhere,” he said.  “I don’t know how she managed to survive… given the car accident… and the damage to that car, I’m confident that 99/100 times nobody walks away from that accident, but Kat did,” he said.  Ms Bautista's relieved parents following the news their daughter was alive. (9NEWS)  Det. Sgt. Giles also said she is in remarkably good health and in good spirits.  “The very first moment when we actually approached Kat and she started to speak I just turned and rang dad straight away and let him know, and you can imagine his response to that,” he said.  Ms Bautista is recovering in hospital and is yet to be formally interviewed by police.  Do you have any news photos or videos?
