Telstra said its group managing director of human resources, Andrea Grant, has decided to leave the company this month.
Grant, who left Telstra on March 18, was appointed to the role in October 2005.
Telstra has started a search for Grant’s replacement. Until a permanent appointment is made, Tracey Gavegan, a senior executive in Telstra’s human resources business unit, will lead the function, the company said in a statement.
