This guide will let you know how to get RICH in Dinkum.
First, you have to go to your tent and talk to Fletch and get certain licenses by using blue tickets in the upper right corner.
The second step is to invite John to the island, the first building you get in the game which has all the important things. You will need 6600 dinky dose to purchase the metal detector as it will help you in making alot of money.
Take this metal detector and start scanning the ground and you will find some blueish spots on the ground, shovel it up and then break it. After breaking it, you will get old-world resources, some of them are worth a lot. You must try your best to get these as much as you can by scanning the ground.
Going along the edges of the rivers has a very high rate of trash in it. The shiny discs are also very expensive. You can sell these to Franklin when he visits but doesn’t sell them to John. Every single disc is worth an 8800 dinky dose.
Smooth slates, motors, and things like that have a high worth. Smooth slates are not rare but the motors are very rare. If you get a barrel that is under the water, you need to drop the dirt back onto it. Digging a lot on the side of the river, you will find a lot of garbage, you have to pick it up, and, you can make a ton of money with this. Also, you will need a lot of things for crafting. If you need to upgrade something in your area, you don’t need to be afraid of selling these. This is a great way of getting a ton of money. 
You also need to find old keys which are really valuable and will help you in deep mining.
Now see how much money you have made by working with this metal detector. Go to John’s shop and sell these items but don’t sell the shiny discs here. You can make it with just a couple of minutes of farming.
