Bushfires that swept through the Adelaide Hills early last month have resulted in 936 claims worth $33.1 million.

The Insurance Council of Australia declared a catastrophe after the fires destroyed 27 homes and burned almost 13,000 hectares.

More than 134 people were injured, most of them firefighters, and many animals were killed.

The fires started on January 2 and it took six days to bring them under control.
