A 22-year-old man has died in his truck as he tried to flee a bushfire raging on Kangaroo Island's southern coast.
The man was found dead in the burnt out truck near Vivonne Bay yesterday.
Initial investigations revealed the vehicle had crashed.
Police forensic officers were heading to the island today to conduct further inquiries into the death and prepare a report for the South Australian coroner.
Assistant Commissioner Madeleine Glynn said it was not yet clear whether the man died as a result of the crash or the fire.
“At this stage it's being investigated as a vehicle collision,” she said.
“But certainly, subsequently or as part of that the fire went through and he and his truck were burnt.
“Which came first, we're not quite certain.”
The Country Fire Service (CFS) said 12 fires, all caused by lightning strikes, threatened properties at various locations on the island, destroying at least one shack and killing 300 sheep.
Seven fires were still burning today with the CFS expecting them to continue to pose problems for at least the next 48 hours.
Properties in various locations remained under threat.
The CFS said it still had 270 firefighters on Kangaroo Island while police declared the western side of the island a dangerous zone, prohibiting the movement of people into those areas.
Firefighters have also been busy with several blazes across New South Wales overnight.
Fire crews were called to a factory fire at Wagga Wagga, in the state's south, about 2:00am (AEDT).
About an hour later, a fire broke out in a loading dock underneath shops and flats at Fairfield, in Sydney's south-west, forcing the evacuation of eight people.
Superintendent Terry Farley, from the NSW Fire Brigade, says there were more evacuations on the South Coast.
