There are a number of interesting books that cover the Broome industry.
Cannibal Nights by a Captain Raab is one, a colorful anecdotal history of sorts. Suggest also
The Pearl Trader (by a dealer) and
Pearl Diver These are all biographies written in the early 20th Century and can be purchased fairly inexpensively from sites that specialize in rare and out of print books. Try

For someone with your interests may I also humbly suggest my own book:
Secrets Of The Gem Trade, The Connoisseur's Guide To Precious Gemstones www.secretsofthegemtrade.com
