In Australia, most of the population lives in a temperate coastal climate. Until recently, evaporative air conditioners had proved popular but prolonged drought conditions have restricted water supply, making these units less attractive. Electrical heat pump air conditioners now dominate the market as they are now more affordable than in the past and also allow winter space heating. Air conditioning ownership amongst households now exceeds 70% in Australia.
