His appointment was confirmed by the AOC’s chief executive Matt Carroll.

Day will depart Australian Rugby Union, where he held the same position for the last seven years, to take up the new role. 

Day, who has been in corporate accounting and financial management for more than 20 years, is due to begin his work with the AOC on September 4.

"I am very much looking forward to joining the AOC," he said.

"I am hoping to integrate my experience and skills from working in the sporting and corporate worlds to help the AOC move forward in what is an exciting time for the organisation."

Carroll claimed Day will help the AOC as they look to broaden their business operations and responsibilities.

"The AOC business is rapidly evolving in a number of key areas including the increased number of teams, expanding involvement in community, health and education with philanthropic opportunity and the increasing complexity of commercial partnerships," he said.

"Todd’s experience and understanding of the nuances of the sport industry will be welcome."

Day replaces Sue O'Donnell, who left the role earlier this year.

O'Donnell was mentioned in a letter written by former AOC employee Ryan Wells as one of the staff members allegedly bullied by media and communications director Mike Tancred.

Tancred, who denies the claims, was "severely reprimanded" but cleared of bullying following an investigation.

Another of the alleged victims was Fiona de Jong, the AOC's former chief executive.
