A serious bushfire south of Adelaide has been contained the Country Fire Service says. FIREFIGHTERS have protected a South Australian country town from an out-of-control bushfire, with two fire crew volunteers injured while quelling the blaze. An emergency alert was issued at 3pm (AEDT) on Saturday about a serious bushfire burning towards the town of Mallala, north of Adelaide. About 200 Country Fire Service (CFS) personnel battled the blaze at Lower Light with 35 appliances and the help of water bombers. A CFS spokeswoman said firefighters contained the blaze after it had travelled seven kilometres in three hours. "The fire was fast-moving and came close to a farming community and within three to four kilometres of the Mallala township," she said. But fortunately CFS firefighters managed to protect the township. A male CFS firefighter was taken to hospital with non-life-threatening chest injuries. A female CFS firefighter was treated at the fire for smoke inhalation.
