The Department for Environment and Water says the objectives of its latest prescribed burn at Seal Bay had been met.
A spokesperson said edge burning was conducted in spring last year and the 39.3-hectare block was completed last week as part of DEW's autumn program of prescribed burning.
Kangaroo Island rangers were aided with the assistance of aerial ignition and DEW crews from the Adelaide and Mount Lofty Ranges region.
People can still expect to see smoke well within the burn block where the fire is naturally patching itself out, Crews continue to patrol the burn and will do so until the area is safe.
The objective of the Seal Bay Conservation Park burn was to reduce fuels in the area to prevent the spread of bushfire.
It is part of a statewide program of prescribed burning planned to protect communities and assets at risk.
