An independent investigation into four claims against Tancred found none of the complaints are "made out on an objective basis".

Tancred stood down from his job in April on full pay, pending the outcome of a separate bullying claim made by former AOC chief executive Fiona de Jong.

In de Jong's case, the independent panel found Tancred guilty of "disreputable conduct" but cleared him of bullying as his actions were not repetitive. 

He was given a severe reprimand.

Four other bullying claims against Tancred - three from current or former AOC staff and another from a person outside the organisation - were then referred to an independent investigation led by former High Court judge Ian Callinan and ex-New South Wales Supreme Court judge Greg James.

Tancred was severely reprimanded in June for telling de Jong he would "bury" her in a phone call between the pair late last year.

Four other complaints, one known to involve former AOC employee Ryan Wells, were investigated.

Tancred was accused of threatening to kill Wells and swearing at another employee at in front of AOC staff.

One employee claimed to have been harassed by Tancred for taking time off work during the 2008 Olympics after suffering a miscarriage.

But none of the allegations were upheld by Callinan and James. 

"The Independent Committee has found that none of the complaints has been made out on an objective basis," the AOC said in a statement published today.

Tancred hopes to return to his AUD$330,000 (£200,000/$262,000/€220,000) per year role at the AOC shortly.

There is speculation, however, that he may still leave the AOC following the investigation. 

Tancred is a big supporter of its President President John Coates. 

"I am relieved that the truth has finally come out," Tancred told the Australian Associated Press.

"I have faced four complaints in 18 years and, although I am not an angel, I'm very passionate about what I do.

"I'm not a bully."

A spokeswoman for the AOC claimed it would be the decision of new chief executive Matt Carroll of whether Tancred returned to work or not. 

The claims against Tancred came amid wider scrutiny of the AOC workplace, which a separate investigation found was dysfunctional.

An Ethics Centre report found many AOC staffers reported senior leaders within the peak Olympic body undermined and were hostile towards each other, and expressed concerns about favouritism and poor communication.
