Flare-ups across the Kangaroo Island bushfire are expected to continue for up to two weeks, as fire crews battle to bring it fully under control.
The blaze has already burnt through 210,000 hectares inside a 588-kilometre perimeter, destroying 65 homes and hundreds more buildings.
The Country Fire Service says it is still burning in various spots along the 120-kilometre eastern flank.
Almost 400 firefighters are still deployed on the island with 83 fire trucks supported by 130 farm fire units.
Five water-bombing aircraft are also being used with four observation aircraft helping target their efforts.
CFS chief officer Mark Jones said crew rotations were continuing to ensure the wellbeing of personnel.
"We're trying to rotate crews as much as possible, but to their credit, people keep putting their hand up and volunteering to go," he said.
"At this time I'm not concerned. We've got lots of resources on the island.
"But, of course, I'm sensitive to the demands that have been placed against these volunteers."
Cooler conditions across the fire zone in the coming days are expected to give the CFS a better chance to deal with the areas of most concern including Stokes Bay, Cygnet River, Vivonne Bay, Seal Bay, Seddon and Birchmore.
