  • World deserts cover 45 million km2, approximately 30% of the global land surface. About one billion people occupy these areas. Australia’s 5.3 million km2 of desert is about 11% of this total.
  • The 5.3 million km2 of desert in Australia is occupied by 574,000 people (3% of the total population).
