Goldie was born in Melbourne just before the 2nd World War. Her parents had migrated from Poland in the late 1920's, and when she was small, she hardly spoke any English. Her earliest memories are of a time when young children were allowed to wander the streets without anyone worrying too much about them getting into trouble.

Her first four Young Adult books were 'Dolly Fiction' novels published under the pseudonym of Gerri Lapin. Her first book under her own name, Mavis Road Medley, is a time travel fiction exploring the world of Princes Hill and her parents' struggles to survive the Depression. Since then Goldie has written more than 35 books, and many short stories and articles.

These days Goldie works full time as a writer, teaches creative writing and lectures and takes workshops in Universities, TAFE colleges, clubs and schools.

She has been a co-winner in the 2000 and 2001 Mary Grant Bruce Award for two long short stories, and is known for her historical, science fiction and mystery novels, plus her short stories and non fiction work.

When Goldie isn't writing and revising, she enjoys spending time with her family and friends, reading, watching DVD's, walking - both in the city and the country - cooking and knitting. She says knitting is a great way to meditate and come up with new ideas.
