KEY POINTS:
Firefighters will be brought in from Victoria, New South Wales and Tasmania as the battle continues against three big bushfires on South Australia's Kangaroo Island.
A huge aircrane helitanker, capable of carrying 9000 litres of water, arrived on the island from Victoria as fears are held for heritage and farming land, wilderness areas and properties. A return to hot and windy conditions later this week, also was a concern.
The Country Fire Service said five strike teams from Victoria were due to arrive and five more would come from NSW and Tasmania tomorrow, adding 250 personnel to the fight.
The service said the blazes in the Flinders Chase National Park, at Western River on the north coast and at D'Estrees Bay on the island's south coast were still burning strongly.
Two other fires, at Vivonne Bay and Riverleas, have been contained.
In the Flinders Chase National Park the blaze had destroyed more than 5200ha and was now burning in wilderness and scrub.
At D'Estrees Bay significant backburning was completed but the service said it remained a concern because it was burning in inaccessible terrain. It already had destroyed about 9600ha.
Backburning operations also had been completed at Western River but the potential for the blaze to break through containment lines on its eastern flank remained high.
