This programe is a small clipse into the lives of people effected by the bug of opal-fever of colour and the potential to get rich quick, as the episodes suggest! But in-the-end, when these people are doing is very dangerous, not too mention the posibility of being robbed for their opal. Note that individual miners will invent there own terminologies to desbribe what they are doing in the process of opal mining. And yes it would appear that the producers are trying to create an atmosphere of dangerous urgency or desperate need to survive either from the mining or life-style. Though Its shows people what takes to mine and in this case aussie opal and practicality of what is needed and science uised but little geologist help not used in the episodes I watched in season 1. Still a great watch if you are like me ans wish you could mine for opal but know that will never happen! DJ
