Australia has a varied climate, leading to different locations around the country having different heating and cooling requirements. To account for these differences the energy efficiency Deemed-to-Satisfy Provisions vary from location to location and for simplicity, locations with approximately similar climates have been combined into eight climate zones.
The following provides a brief description of each NCC climate zone:
Climate Zone 1
High humidity summer, warm winter
Climate Zone 2
Warm humid summer, mild winter
Climate Zone 3
Hot dry summer, warm winter
Climate Zone 4
Hot dry summer, cool winter
Climate Zone 5
Warm temperate
Climate Zone 6
Mild temperate
Climate Zone 7
Cool temperate
These eight climate zones are illustrated in the form of a climate zone map which was created using Bureau of Meteorology climatic data with two supplementary zones added to accommodate an additional temperate zone and alpine area. The climate zone boundaries are also aligned with local government areas and are therefore subject to change from time to time.

Australia is a varied climate with different locations requiring different heating and cooling needs. Accounting for these variations in climate, the Energy Efficiency Deemed-To-Satisfy has, for simplicity, allocated locations that are approximations of one another in terms of what their general climates are like. As a result, there are eight climate zones, described briefly below.
Climate Zone 1
Warm winters and high-humidity summers
Climate Zone 2
Mild winters and warm, humid summers
Climate Zone 3
Warm winters and hot, dry summers
Climate Zone 4
Cool Winters and hot, dry summers
Climate Zone 5
Warm in temperature
Climate Zone 6
Mild in temperature
Climate Zone 7
Cool in temperature
These zones are illustrated below in a series of diagrams that have been sanctioned by the Bureau of Meteorology. Two additional zones have been added to account for alpine and temperate areas. The eight zone-boundaries are subject to changes over time as they are (in some cases) aligned with local government. The map is relevant to the State of Victoria.
