A bushfire has come close to homes in the Adelaide Hills as South Australia swelters through extreme weather conditions.
The Country Fire Service (CFS) had about 200 firefighters supported by six aircraft tackling the blaze near Rockleigh.
It burnt strongly for much of Wednesday, destroying about 1000 hectares of grassland as it headed towards the town of Callington.
It came within about one kilometre of homes before a wind change but was still listed as uncontrolled.
Temperatures across SA surged above 40C with conditions forecast to get worse on Thursday.
The Bureau of Meteorology said Adelaide could expect 43C with 45C forecast for some regional centres.
A cool change was not expected across South Australia until late on Friday.
