welcome to the page Suzie
what are you interested in more , gold or gemstones ?
You are close to some of the best country for gold where you are , in fact some members from other parts of the country travel to WA from May to September to use metal detectors in their hunt.
Its not always easy but many people find enough to cover their costs and on very rare occasions you will hear of people who get enough to retire on.
When it gets too hot in WA the Eastern States become more attractive for wet prospecting ( using sluices , pans or high bankers ) to search for gold
have a good read here , learn about the safety aspects like taking PLB devices in case you get into trouble , learn basic first aid , how to understand snake species , behaviour , protection and response to them and get together with a few locals
you might even find some prospecting clubs near you to go out on trips with
best wishes
