His donation of €6 million for the "Isombululo" programme for the prevention and treatment of HIV/AIDS was announced at the Presidents Cup, one of the world's leading international golf tournaments in 2003 and it is suggested that this amount will have helped 360,000 people. In the spring of 2005, Plattner personally covered the costs of the 46664 benefit concert, which took place at his Gary Player-designed golf course, The Links of Fancourt in George which is near Cape Town and which was broadcast globally on television. Proceeds went towards the former South African president Nelson Mandela's fund to fight HIV/AIDS.
