Earthmoving equipment, water tankers and extra fire crews are being sent to strategic locations on Kangaroo Island ahead of a day of high bushfire risk.
The blaze on the island is officially contained but the Country Fire Service says crews are still finding hotspots in various areas including Blue Gum Hill, Cygnet River and Vivonne Bay.
The bushfire risk on Thursday is expected to be severe with a total fire ban to be put in place as temperatures soar.
Adelaide is forecast to have a top of 42C with the mercury going even higher in some regional centres.
The CFS said 75 firefighters and 24 trucks would work to strengthen control lines ahead of the high-risk day.
The blaze was sparked by lightning on December 20 and flared dramatically on two occasions in late December and early January.
It has burnt through more 210,000 hectares and destroyed more than 50 homes along with hundreds of other buildings, crops, livestock, wildlife and infrastructure including many kilometres of fencing.
It also claimed two lives, with father and son Dick and Clayton Lang killed when their car became engulfed in flames.
