Malcolm Speed is to step down from his position as chief executive of the International Cricket Council in June.
Speed took over as ICC chief in 2001 from Dave Richards
Cricket's world governing body says Speed, 58, will not seek an extension of his deal when it expires in 2008.
"He made a decision ages ago that he was not going to seek renewal of his contract," said an ICC spokesman.
"It has long been Malcolm's intention to retire at 60 and his current contract takes him a couple of months short of his 60th birthday."
Speed headed the Australian cricket board prior to succeeding Dave Richards as the figurehead of the ICC.
During Speed's reign the ICC departed Lord's, the body's home for almost a century, to move to Dubai in 2005.
Recently he came under fire for the seemingly never-ending World Cup and was at the centre of the Darrell Hair affair last summer following the forfeited Test between England and Pakistan at the Brit Oval.
