Five fire fighters have been injured and a house has been destroyed as a bushfire rages out of control south of Adelaide.
Waterbombers and 160 fire fighters are battling the blaze near the historic town of Willunga, 47km from Adelaide, as the tinder-dry region swelters through its longest-ever heatwave.
The fire started about 3.30pm CDT on the edge of the winegrowing region of McLaren Vale, a Country Fire Service (CFS) spokeswoman said.
The blaze had burnt about 100ha of land by 5pm CDT.
"Unfortunately we have lost one house," she said.
Four or five firefighters were injured and were transported to the Willunga oval and treated by SA ambulance for minor injuries, an ambulance spokeswoman said.
Residents are being warned to activate bushfire plans and note there are roadblocks in place.
People who commute to the city should consider remaining there tonight, the CFS spokeswoman said.
The CFS says the fire is burning in a south-westerly direction along Bishop Road and is heading towards Meadows and Proctor Roads, driven by strong winds.
Adelaide, still in the grip of drought, surpassed today the previous capital city heatwave record of 10 days above 35 degrees recorded in Perth in February 1988.
Fire bans are in force across the state tomorrow.
