About the regions

Southern Australia can be divided into four broad agro-climatic regions:

• Temperate, cool seasons, wet, high rainfall (southern Victoria and NSW tablelands)
• Classic ‘Mediterranean’ climate with cool, wet winters and warm to hot, dry summers (south-west WA and southern SA)
• Mediterranean climate with drier, cooler winters, and with more summer rain in the eastern states, than the above regions (inland south-west WA, southern SA, north-west Victoria and southern NSW)
• Temperate, sub-humid (NSW western slopes).

Within these broad regions further division is necessary to determine the best perennial plant options. Therefore, these regions have been divided into 12 regions based on rainfall (including occurrence of summer rain), minimum winter temperatures, soil type and soil pH.

Within these 12 regions, the dominant climatic feature varies. For example, in WA average annual rainfall is the dominant feature and, within each region, mean monthly temperatures will vary, being warmer in the north and cooler in the south.
