This work investigates the high-stakes, perilous world of the Australian pearling industry in the early 20th century, focusing on the physical and economic realities of deep-sea diving. Ion L. Idriess, a prolific chronicler of the Australian frontier, draws upon his own experiences and extensive interviews with divers to document the technical challenges and social dynamics of the pearling fleets. The book presents a detailed account of the dangers inherent in the trade, from the physiological toll of the bends to the volatile nature of the sea and the men who sought fortune beneath it.

This text is regarded as a significant historical record of a rugged and often overlooked Australian industry. The narrative provides a dense, atmospheric look at the maritime frontier that remains a primary source for understanding the development of the North West region.
