During the rainy season there is little to be had at the Palmer River Goldfields in Australia. So Mat and his buddy Andreas Macherey are looking for an alternative prospect. About 500 miles away on the Cape York Peninsula, the treasure hunters have discovered a promising area that they want to test for gold deposits. However, the terrain is very rough. For this reason, the men switch from four wheels to four legs and ride horses through the bush Down Under.

Things rarely go according to plan in the Palmer River goldfields. But that doesn't upset treasure hunter Andreas Macherey and his buddy Mat: Because then Down Under Plan B will come into play! The men need more steel so that they can continue building their wash plant. But the dealer has delivery problems. Therefore, the adventurers use the time and straighten the access route to the camp - so that the freight can be delivered to the Australian bush at all.

Mats Mine Down Under is located approximately five hours from Cairns in the Palmer River Gold Field. After numerous visits in recent years, it has become Andreas Macherey's second home. In the next three weeks, the men want to build a large wash plant there. No easy and no cheap undertaking: But the investment could pay off, because the capacity of the shaker is enormous. With its help, the duo can mine the precious metal deposits much faster than with gold pans.

Gold fever drives Mat and his German buddy Andreas into the Australian bush. There, the two adventurers use detectors to search for precious metals. Then it's time to roll up your sleeves, because treasure hunting is hard work. The duo build a camp for Andreas on the Palmer River Goldfields in Queensland. Will the men Down Under be rewarded for their efforts or will their big dream soon go up in smoke?
