Suurim jõgi on Murray (2740 km) koos lisajõe Darlingiga (2740 km). Energiarohkete Ida-Austraalia jõgede vett kasutatakse peamiselt põldude niisutamiseks ja karjamaade veega varustamiseks. Tähtsad niisutus- ja hüdroenergeetilised seadmed on rajatud Murray, Murrumbidgee, Lachlani ja Swani jõele. Austraalias leidub rohkesti järvenõgusid, mis ajuti täituvd veega. Suurimad neist on Eyre, Torrens, Amadeus ja Gairdner. Edela-Austraalias paikneb palju väikesi soolajärvi. Austraalia majanduselus on suur tähtsus arteesia veel, mis lasub 1,5-2 km sügavuses ning seda võib leida näiteks Kesk-Madaliku alt. Et arteesia vesi sisaldab palju sooli, kasutatakse seda peamiselt tehniliseks otstarbeks ja karjamaade niisutamiseks. Enamik järvedest asub riigi kuivas ja tasase pinnamoega siseosas, kus nende pindala on sõltuvuses sademete hulgast eri aastatel.
Recently a black coral was found. Tourists visit it because it is beautiful, relaxing and interesting. Lakes The big lakes of the desert area are dry most of the time. Enormous Lake Eyre (70km wide, 130km long) was dry for a hundred years until 1950. Lake Eyre is the lowest place in Australia. It is 16 meters below sea level. Other bigger lakes are Lake Disappointment, Lake Mackay, and Lake Carnegie in the western part. Lake Torrens, Lake Gairdner and Lake Eyre in the southern part. Rivers The biggest river is the Murray. The other biggest rivers are the Mitchel and the Flinders. Other rivers are short and have water only after rains. The Climate Australia stretches from the tropics to the temperature region. It is a hot and dry country. The northern part has a hot tropical climate with heavy rainfall. It has two seasons - wet summer and dry winter. The south and the east of Australia have warm summers and winters.
Of other trees there grow bottle trees in the savannas, tree ferns in the tropical forests and many others. Lakes Australia has much underground water. There are only few lakes which are full of water only after it rains. The biggest lake is Lake Eyre which is a salt lake. The natural lakes of the interior of continental Australia are salt lakes. Fed by streams and rivers, they receive water rarely. Lake Eyre, Torrens, Frome and Gairdner are the remains of a vast inland sea which once extended south from the Gulf of Carpentaria. Rivers Australia has only few rivers. Many of them are full of water only after it rains. There are many temporary rivers called creeks. The biggest rivers are in the east. All the rivers in Australia are short. Murray River is Australia's principal river. The Murray River and its tributaries run approximately 3,370km in length and form most of the border between New South Wales and Victoria.
