Just outside a small town Moorina is the river called Weld, which is renowned for its Sapphires, Party Sapphires and Topaz.
This is a public fossicking area where no license is required if you are happy to fossick on the lower side of the bridge, if you intend to fossick up stream a license is required and these are available from the MRT website. You will need a set of sieves and or a gold pan and a long handle shovel
Camping both nights either at the on the grassland behind the Weldbourough Pub.
Limited phone service , No showers or toilets in the area so a good shovel will be required.
Dogs are allowed but must be kept on a lead at all times, parents will have to keep a close eye on their children as the river can be deep in places, river runs behind both camp spots.
BYO Food and Drinks.
