Sheep are raised on Kangaroo Island and the southern tip of Eyre Peninsula. An important Tuna industry is based at Port Lincoln . Rainfall is low to moderate, the highest falls are at the southern tip of Eyre peninsula and the west of Kangaroo Island. Around 250mm is the lower limit for wheat crops. It is only because the low rainfall comes in fairly reliable winter showers that wheat can be grown at all.
Summers are usually very dry and almost rainless in the north.
Similar rainfall totals in Queensland and the Northern territory are desert. Summer daytime temperatures are variable, the southern parts may have some cooler, cloudy summer days. Hotter periods are common, especially around Ceduna where any wind from East to Northwest is coming from the interior deserts. Winter temperatures are cool to mild. Snow is not a normal part of the climate and I could find no reports of snow having fallen in these areas.
