A world-renowned Adelaide plastic surgeon will fly to Greece today to treat victims of deadly wildfires with Australian-developed skin repair technology.

Dr John Greenwood will assist Greek surgeons with the 10 most severely burned patients from the fires near Athens that have taken at least 82 lives and injured many more.

He will begin work on Sunday at the KAT Hospital in Athens using a biodegradable skin graft substitution he pioneered with the CSIRO after the Bali bombings in 2002.

Dr Greenwood is director of the Adult Burns Unit at Royal Adelaide Hospital and was 2016 SA Australian of the Year for his world-leading work in burns treatment.

The skin graft product, called NovoSorb, made by Melbourne-based company Polynovo, acts as a dermal tissue scaffold allowing new dermal cells, blood vessels and skin structures to develop, leaving soft, supple skin with minimal scarring.

The product is considered a game-changer for burns treatment.

Meanwhile, Greek authorities say they have "serious indications" the wildfires were set deliberately.

Public Order Minister Nikos Toskas said satellite image analysis and ground inspections suggest the fire that broke out in multiple places in a short time frame on Monday likely resulted from arson.

The death toll from the fire that swept through a coastal area east of Athens has risen to 82 as the search for more victims on land and at sea continued.

Germany's federal criminal police department says a team of its forensics specialists is in Greece to help officials there identify victims from this week's deadly forest fires.

The team includes veterans of such major disasters as the 2002 midair plane crash over Ueberlingen, Germany that killed 71 people and the 2004 Indian Ocean tsunami that killed at least 225,000 across multiple Asian countries.

The chief coroner in Athens says the task of identifying victims is difficult because most of the bodies at the morgue were severely burned.

Another complicating factor is wind-whipped flames raced through a large area. Authorities are working to put together a complete list of those missing.

Meanwhile, a spokesman for the Belgian foreign ministry says a Belgian tourist was killed as he tried to flee blazes in the summer resort of Mati north of Athens.

The spokesman, who spoke to the Associated Press on customary condition of anonymity, said the tourist was among a larger group staying at an area hotel that was ordered evacuated to the nearby sea as the flames approached.

But he said the exact circumstances under which the Belgian man died during Monday's blaze are unclear.
