Airservices says chief executive Margaret Staib will leave the organisation in August for health reasons.
The nation’s air traffic navigation services provider said on Friday Staib would “not be renewing her term in October and will leave Airservices in August”.
“Ms Staib’s decision has been prompted by her decision to focus on her short term personal health,” Airservices said in a statement.
The Royal Australian Air Force (RAAF) Air Vice Marshal and former RAAF Commander Joint Logistics was appointed Airservices chief executive in September 2012.
Airservices chairman Air Chief Marshal Sir Angus Houston said Staib had made a significant contribution during her almost three years as chief executive and “achieved considerable success”.
“Ms Staib will be missed by colleagues and Airservices wishes her every success in the future,” Sir Angus said.
As chief executive, Staib oversaw the signing of contracts for the new Onesky air traffic management system, which aims to combine Australia’s currently separate civil and military air traffic management systems into one program.
Sir Angus said Airservices was in the process of selecting a new chief executive.
Meanwhile, Jason Harfield, Airservicves executive general manager for future service delivery, has been appointed as acting chief executive.
