I thought this was in the title, but have had no luck. Set in Western Australia, for some reason a teen ends up surviving on their own (maybe a girl) and before rescued burns wood for a fire which actually turns out to be the petrified remains of shipwrecked sailors from the Batavia or other Dutch (maybe) craft involved in spice trade to Indonesia. I really just remember that the key protagonist thinks she’s hallucinating when spirits appear in the smoke. Can’t remember why he/she is alone, maybe family break down or similar. Presume “stone forest” refers to Bungle-Bungles of the Kimberley region of northern Western Australia. Fairly modern, so maybe published in the 1980’s?
