The CFS had earlier warned residents to take action with the bushfire threatening those who weren’t prepared to leave.
“Do not enter this area as conditions are dangerous,” CFS tweeted earlier.

The winds are expected to continue bringing dust into residential areas throughout the night, and the Bureau of Meteorology issued a severe weather warning for damaging winds for regions including Kangaroo Island, Lower Eyre Peninsula, Yorke Peninsula and parts of Mount Lofty Ranges, Eastern Eyre Peninsula and Mid North districts.
