The Antarctic ozone hole is about one-third to blame for Australia's recent series of droughts, scientists say.
Writing in the journal Science, they conclude that the hole has shifted wind and rainfall patterns right across the Southern Hemisphere, even the tropics.
Their climate models suggest the effect has been notably strong over Australia.
Many parts of the country have seen drought in recent years, with cities forced to invest in technologies such as desalination, and farms closing.
The scientists behind the new study - led from Columbia University in New York - added the ozone hole into standard climate models to investigate how it might have affected winds and rains.
"The ozone hole results in a southward shift of the high-latitude circulation - and the whole tropical circulation shifts southwards too," explained Columbia's Sarah Kang.
