"Let us all never forget that only education can be the final key to eliminate poverty in the world and raise the universal standard of living, ultimately to increase the nobility of the human cause," Forrest said in a statement.
Forrest and his wife Nicola are the first Australians to join "The Giving Pledge" movement founded by Microsoft Corp. co-founder Bill Gates and investor Warren Buffett, the head of Berkshire Hathaway Inc. The pledge commits billionaires to donate most of their wealth to charity.
Anna Draffin, deputy chief executive officer of the charity umbrella group Philanthropy Australia, described the Forrest gift as the biggest ever philanthropic donation from an Australian.
Only Irish-American businessman and philanthropist Chuck Feeney has been more generous in Australia, donating AU$500 million toward mostly higher education and medical research projects.
