Idriess, a prolific Australian author known for his immersive accounts of the outback and frontier life, draws upon his own experiences and extensive research to document the lives of those working beneath the surface. He presents a detailed examination of the economic, social, and physical challenges faced by divers, crew members, and entrepreneurs operating in the treacherous waters of the North West coast.

The narrative provides a dense, atmospheric look at the industry that remains a primary reference for those interested in the social and economic development of Australia's North West.
