Arnhem Land, is one of Australia's largest nature reserves. In the northern peninsula region, it is bordered by the Arafra Sea to the north, the Gulf of Carpentaria to the east, the eastern shore of Van Dimen Bay to the west, and the Ropo River to the south. It covers an area of about 80,000 km².
There are many harbors along the coast, and it has a savannah climate. Most of them are low plateaus, and the highest central part is 366m above sea level.
In summer, the west and northwest winds blow mainly in this area, with more precipitation, abundant river water, and long-term erosion by the Victoria River, the Ode River, and the Fitzroy River, and the surface is rugged and the scenery is magnificent. It was once called "the most primitive, undeveloped and uninhabited place in the world today".
There are thousands of bison roaming the vast sea, and the indigenous people have established their own special way of life. Like the spirit of the early American pioneers of the West, many tourists come here on expeditions to see this remote, pristine natural landscape and indigenous ruins.
The cliff wall is like cutting, the stone layer is folded, gray and yellow are mottled, and the green trees are thick. The dam of the Oder River is formed by the Gelai Lake, and there is a red rock island in the lake, which is home to kangaroos.
The Jim Jim Twin Waterfalls, the huge Aboriginal gallery Nolaugi Grottoes, the gorges and caves on the banks of the Catherine River are all must-sees.
The Kakadu region of the Aligate River basin was the first place where the indigenous people lived, and they gradually spread across the continent.
The natural beauty of the Kakadu region, rugged and spectacular, cultivated the unrestrained character of the indigenous people, as well as the beauty of gathering humanity and nature, and the Kakadu National Park was established in the early 80s.
On the east bank of the Oder River, in the town of Kununurra, there is an alluvial plain research station, and the nearby Gove region is rich in bauxite.
