The remote nature of prospecting makes it inheriently risky, even when with a friend or group. Should there be a requirement for a prospecting ticket, similar to a skippers ticket?
It would be free and you could apply for online, it would be a one off. To get the ticket you would have to complete some online training about the legislation and safety requirements, there would be a requirement for safety equipment such as a Personal Locator Beacon or satellite device with an emergency message / SOS option. On completion of the course / ticket you could get a discount for one of these devices or be able to have some of the costs refunded. Property owners and police could ask to see your ticket, and there may be a fine if you are prospecting and don't have one.
I am from WA and hear of horror stories of prospectors new and experienced taking only a mobile phone for their communication and directions and not bringing enough water for an emergency. It is tragic when prospectors go missing, and it uses paid and volunteer emergency services time and energy and deaths from people being unprepared are preventable.
