Stephen (Steve) Killelea AM is an Australian IT entrepreneur. He began his career, after doing a crash course in computing and working for a computer manufacturer, by developing a product for computer systems management that became internationally successful and led him to set up a US company, Software Products, that went public.
In August 1988, Killelea formed the Australian company Integrated Research, which was listed on the Australian Stock Exchange in 2000. The company's main business is systems management for international corporations such as Visa, Mastercard and American Express; the New York, London and Hong Kong stock exchanges; and most of the world's ATMs. Having stepped down as chief executive November 2004, he is still chairman of the company that now branches into the field of internet telephony. Killelea also has an IT venture capital fund.
He set up the Charitable Foundation in 2000, which is one of Australia's biggest private overseas aid providers, spending over five million A$ in 2008. Killelea is the creative force behind the Global Peace Index study, launched in May 2007, that attempts to rank the world's nations’ and regions’ peacefulness. The Index is endorsed by the Dalai Lama, Desmond Tutu and Jimmy Carter. He is the founder of the Institute for Economics and Peace which is "analysing the impact of peace on sustainability, defining the 'Peace Industry', estimating the value of peace to the world economy, and uncovering the social structures and social attitudes that are at the core of peaceful societies". He is also notable as being Australia's largest individual donor to overseas aid. He also sits on the advisory board of the Alliance for Peacebuilding.
In 2008, Killelea was the producer and chief financier for the documentary Soldiers of Peace, which was shown at the 2009 Cannes Film Festival, where it received The Club of Budapest World Ethic Film Award. The documentary also won Best Feature Film at the Monaco International Film Festival.
In June 2010, Steve Killelea was appointed a Member of the Order of Australia for his service to the community through the global peace movement and the provision of humanitarian aid to the developing world.
