Commissioner Gaughan was adamant no-one should be above the law.
"No sector of the community should be immune to this type of activity or evidence collection more broadly," he said.
"This includes law enforcement itself, the media or, indeed, even politicians.
"There are criminal allegations being investigated and we cannot ignore them. We are duty bound to conduct these investigations impartially and thoroughly."
The Australia Federal Police chief has warned that journalists and MPs are not immune from criminal prosecutions, leaving open the possibility of jail terms for those found to have broken the law.
“Our investigations are an objective search for the truth. It involves the discovery and presentation of evidence in an exhaustive, comprehensive, and organised manner. No sector of the community should be immune to this type of activity or evidence collection more broadly.
“This includes law enforcement itself, the media, or indeed, even politicians. There are criminal allegations being investigated and we cannot ignore them.”
In October 2016 I reported to the Commonwealth Attorney General and the CDPP the matter of Gillard's use of a forged letter in sworn evidence to a Royal Commission.
To date, the AFP has not contacted the single witness who could give unimpeachable evidence about the forged letter, the purported signatory Ray Neal.
Today I sent the Commonwealth DPP and Attorney General this letter.

For the avoidance of doubt, I am reporting this matter to you as a report of serious indictable offences. Given the use of the apparently false instruments at the TURC in the process of it hearing false and misleading evidence and the Commissioner's acceptance (in the absence of any enquiries having been made about their provenance) of the Exhibits as good and valid copies of the documents they purport to be, the use of the false instruments is an ongoing offence (particularly to the purported author) and the record should be corrected.
A former WA corporate affairs chief has provided sworn evidence for the criminal prosecution of Julia Gillard over her allegedly misleading and deceptive evidence to the Trade Union Royal Commission.
The prosecution relates to the use of an apparently forged letter during Ms Gillard's evidence to the Royal Commission.
The letter, addressed to Ms Gillard, purports to have been written and signed by Ray Neal, then the Assistant Director of WA's Office of State Corporate Affairs.
On Friday Mr Neal said, "I didn't write that letter."
"I didn't sign that letter."
"I didn't authorise anyone to write or sign the letter."
"The letter contains an unlawful offer. My office could not lawfully have made that offer. My office always acted within the law."
This letter is a forgery.
More to come.
