Who is Aggie Topp from A Town Like Alice and what is their importance?

Aggie Topp is the forewoman at the Pack and Levy leather company. She is described as a gaunt, stern, thirty-five-year-old, veteran A.T.S. sergeant who served during the war in Egypt. She and her husband have been apart for a long period of time, and she is understandably upset by the separation. Pack offered her the position in Australia, hoping to keep her from quitting.
