This is music-related and flood-related:

I lived in Maitland NSW, and my Mother was evacuated about 3 months before I was born because of the devastating flood at that time.

Floods are definitely part of the history of that place.

Synopsis

Mr and Mrs Flynn who live in Maitland, a New South Wales country town, form a musical quartet with Leo, the local greengrocer, and Consuela, a young female bank teller. When Consuela marries and moves interstate, Leo is heartbroken and the trio, dissatisfied with their reduced performance, searches for a replacement. Leo discovers that one of his customers, Dolores Costello, plays the cello. She refuses an invitation to join the group until after he rescues her from the flood which threatens the district. When the floodwaters subside, the quartet resumes their public performances which have a transformative effect on the lives of the townsfolk.
