Former Australia Post exec, John Cox, is taking up a role at Coles as chief technology officer. Cox was previously AusPost’s executive general manager of transformation and enablement.

Cox is just one of several senior leaders at Australia Post who have departed from the company recently, which The Australian described as “a mass exodus”.

Two of the former employees have left to join former CEO Christine Holgate at Global Express – Michael Oates, former manager of mail services and Holgate’s former assistant, Vicki Ballantyne.

Meanwhile, AusPost’s general manger of customer solutions and partnerships Claire Burke is set to leave the company after almost 10 years and Michelle McNally, general manager of property is returning to her former employer, ISPT Super Property.

Chief risk officer Claire Hamilton is leaving for a similar role.

New Australia Post CEO Paul Graham is set to begin his role in September.
