A bushfire in the Adelaide Hills has been contained quickly, with a quick response considered to have played a critical role.
The fire on Gorge Road, Highbury, had 65 volunteer firefighters from the Country Fire Service, join with crews from the Metropolitan Fire Service and Department of Environment, with the fire limited to about 2.5 hectares in size.
CFS firebombing and observation aircraft also played a critical role in helping suppress the fire's forward rate of spread in difficult terrain.
Firefighters will continue to patrol the area and mop up to ensure the fire poses no further threat to the community.
This was one of several fires in recent days as temperatures soared, with all areas of the state declared part of a heatwave, and total fire bans in place across many regions.
