What is the main conflict in The Road from Coorain by Jill Ker Conway?

The Road from Coorain is the autobiography of Jill Ker Conway, a native Australian, historian and the first female president of Smith College. Conway was born in 1934 in Hillston, New South Wales, in the "bush," or Australian "outback," to parents who operated a large sheep station that they named Coorain. Conway had two older brothers, Bob and Barry. While her life in the bush was not filled with other children, she was still happy, social and able to pursue her interests. Her mother, an avid reader and self-educator, taught Conway to read at an early age and Conway read voraciously as a child. She also became familiar with the hard chores required to maintain Coorain.
