The Flying Doctors (1986)

S5E5 No Man's Land

Chris and David arrive at a location for a clinic run, where a mother and her two daughters reside. The family appears to harbor some resentment towards men and is not particularly welcoming to David, who they were not expecting; they had anticipated Kate’s arrival instead. As a result, David ends up staying in the shearer’s quarters. When the older daughter spots her sister kissing a guy in the barn, she storms after him with a whip. Meanwhile, the younger daughter expresses her desire to travel to Sydney to search for their father, a plan their mother vehemently opposes. Eventually, it's revealed that the father had abused the older daughter.
