The feather and the stone - Patricia Shaw

Tragically orphaned at sea, cast adrift in an alien land, Sibell Delahunty applies for the post of secretary-companion to Charlotte Hamilton and undertakes the arduous journey to Black Wattle Station in the Northern Territory.

Only Charlotte's own kindness makes life tolerable, helped, in time, by increasing interest from the unmarried son, Zack.
