The Brumbies Rugby Union team in Canberra has called in police to investigate the controversial sale of its Griffith headquarters in 2013.

Brumbies chief executive officer Michael Jones said there were some unanswered questions about anomalies in the paperwork.

"Myself and the board, when we looked at some of the transactions between 2009 and 2013, we sensed that there was something not right there," he said.

"We took that further with the Australian Rugby Union integrity unit, and KPMG's forensic unit in Queensland to look at a vast number of documents and transactions.

"All those details have been passed on to the Australian Federal Police to assess whether there is any case to answer or any criminality."

The club believes it has taken the appropriate decision from a governance and transparency perspective.

"There were a large number of transactions which took place in that period, of which a lot of them are interlinked in some ways," he said.

"And we haven't made any accusations, or implications in relation to any specific matter.

"It's just that when you take it in its entirety there's something that we are just not comfortable with, and from the board's perspective we believe it was the right action to refer it to the police."

The headquarters moved to a training facility at the University of Canberra in Bruce after the sale of the Griffith site.

The club has confirmed no current staff members were implicated.

The Brumbies CEO at the time of the relocation was Andrew Fagan.

He has since been appointed as chief executive at the Adelaide Crows AFL club.

During a press conference, Mr Fagan denied any knowledge of the alleged irregularities in the sale of the Brumbies headquarters.

"I haven't been contacted and I'm not sure whether I will be," he said.

"Certainly, I'm not across any of the details.

"So therefore it would be really difficult for me to comment."

Canberra University says relationship will not be affected

In a statement, ACT Policing confirmed it had received a referral from the Brumbies and Australian Rugby Union, and said it was "currently being assessed".

But said it was "not appropriate to make any further comment".

University of Canberra vice-chancellor Stephen Parker said the organisation was sorry to hear about the police investigation at the Brumbies, but did not believe it would affect their relationship with the team.

"This collaboration has seen the creation of scholarships for high-performing young rugby players to study an undergraduate degree at the University," Professor Parker said.

"As well as honours students doing internships with the Brumbies' coaching and performance analysis teams, resulting in employment both in Australia and internationally.

"Some of our researchers are also working together with Brumbies players to test accurately for concussion to ensure the protection of their long-term health."

The ACT Government has also released a statement about the police investigation.

"Brumbies chairman Mr Robert Kennedy has told the Government that KPMG had identified a number of unanswered questions in the non-government transactions and agreements relating to the sale of its former headquarters," the statement said.

"The Government has not been briefed about the nature of the KPMG report, but the Brumbies chairman and CEO have assured the Government that the investigation is not looking at agreements and transactions between the ACT Government and the Brumbies.

"As a major stakeholder and sponsor of the Brumbies, it is quite appropriate that the ACT Government was given a heads up that they were referring certain matters to the police. As noted above, this briefing was not about the content of the KPMG report."
