Hugh Evans is an Australian humanitarian and internationally renowned development advocate work speaks to anyone who has ever asked, "What difference can I make?" His resolute belief is that every individual can take meaningful action towards ending extreme poverty within a generation. His work involves creating opportunities for individuals to take action that will have monumental impact.

His journey began in India and South Africa, working with those living in extreme poverty for three years. Upon returning to Australia, he founded The Oaktree Foundation, with a mission to bring young people together to see an end to extreme poverty. Australia's first, and today the world's largest, youth-run aid organization, Oaktree has provided education to more than 40,000 young people around the planet. The foundation also produced the Make Poverty History concert in 2006, fronted by U2's Bono, which mobilized thousands of young people into putting pressure on political leaders, ultimately leading Australia to double its foreign aid budget, releasing $4.3 billion in funds for the world's poor. His achievements as director of Oaktree secured Hugh the Young Australian of the Year award in 2004, and the Junior Chamber International Person of the World in 2005.

Hugh's bold and daring vision has captured the attention of movie stars, business tycoons, and academics alike, from Bono and Hugh Jackman to Jeffrey Sachs and Bill Gates. In 2012, he was listed as part of Forbes magazine's annual "30 Under 30" for social entrepreneurship.

Hugh is now the co-founder and chief operating officer of the Global Poverty Project (GPP), an educational and campaigning organization that activates citizens to be a part of the global movement to end extreme poverty. In 2011, GPP, backed by the Bill and Melinda Gates Foundation, leveraged $118 million in new funding for the eradication of polio—a crippling disease that keeps people in developing nations poor.

Hugh has passionately spoken out against extreme poverty at many forums, including the Commonwealth Day Address at Westminster Abbey by invitation of Queen Elizabeth II, the Sir Keith Murdoch Oration in Melbourne, and the Montreal Millennium Summit alongside Al Gore, as well as innumerable international conferences around the world, including presentations in Singapore and Colombia.

Hugh holds a Bachelor of Science and Bachelor of Laws at Monash University, and has completed a Masters in International Relations at the University of Cambridge.
