The Australian Savanna is characterized by two very different seasons: the "wet" and the "dry". The dry season lasts 5 to 6 months, usually from May to October. The wet season lasts 5 to 6 months and lasts from December to March. The Australian tropical savanna is found along the north coast of Australia at a latitude range of 10° to 20° South.
Usually only grass grows in the savanna, with some scattered trees. If there was no dry season, trees would populate the savanna. Trees do not densely populate them since they need too much water. Because in the dry season it doesn't rain, trees can only grow in the wet season.
