Three frontbenchers in the Turnbull Government have been named in a search warrant executed on a house owned by the parents of former Peter Slipper staffer James Ashby.

Australian Federal Police went to the property at Beerwah on the Sunshine Coast Tuesday morning with a warrant for items that "relate to the diaries of Peter Slipper".

Nine officers searched the property, which Mr Ashby also works out of.

James Ashby has provided the ABC with a copy of the warrant which shows police were looking for mobile phones, SIM cards, computers, electronic storage devices, photographs, diary records and other correspondence.

The search warrant includes mention of Special Minister of State Mal Brough, Industry Minister Christopher Pyne and Assistant Minister for Innovation Wyatt Roy.

The ABC has contacted the offices of all three MPs for comment.

Mr Ashby hit the national headlines in 2012 when he accused his then-boss Mr Slipper, who was then the speaker of the House of Representatives, of sexual harassment.

Mr Ashby later dropped his Federal Court case against Mr Slipper, who had denied the allegations.

Mr Ashby was accused of leaking extracts of Mr Slipper's diaries to the media and to Mr Brough, who went on to win Mr Slipper's Sunshine Coast seat and recently became Special Minister of State in the Turnbull Government.

Ashby shocked by search of parents' house

Mr Ashby, who recently became an adviser and pilot to Pauline Hanson, said he was "shocked" and "disappointed" by the search.

"They're looking for diary records, photographs, correspondence, notes, telecommunications records, travel records, accommodation records, postal records, receipts, spreadsheets, and newspaper articles that relate to the diaries of Peter Slipper," he said.

"Some of those people that they are looking for evidence of is communication with Christopher Pyne, Mal Brough, Wyatt Roy, along with Channel Nine and News Corp reporters.

Mr Brough told Channel Nine's 60 Minutes in 2014 that he asked Mr Ashby to procure a copy of Slipper's diary because he believed Mr Slipper had committed a crime.

Mr Ashby however today said that he volunteered the diary.

"Peter Slipper continues to pursue charges against me for the whistleblowing act of revealing his diary, which later led to charges in Canberra and aided my case," Mr Ashby said.

"Mal Brough never procured me to get those diaries.

"I had copies of the diaries already, I volunteered those diaries to Mal Brough.

"Copies of Peter Slipper's diaries were handed over to the Federal Police when I first made my sexual harassment claim.

"So these guys today will have nothing new, I don't have copies of those diaries."

Mr Ashby alleged Federal MP Graham Perrett and his "best mate" Mr Slipper are keeping the issue alive with the Federal Police because they were bitter that Fisher was lost.

Past catching up with the frontbenchers

Federal Labor's Graham Perrett said there were some serious questions to answer.

"Mal Brough, Christopher Pyne and Wyatt Roy have all tried to run a mile from their roles in this," he said.

"Now their past is catching up with them - it's unravelling by the day.

"It's time they each came clean once and for all about what their roles were."

The third condition of the warrant said there were "reasonable grounds for suspecting that they will afford evidence as to the commission of the following indictable offence(s)"

They include Mr Ashby allegedly accessing Mr Slipper's official diary, which is restricted data, without authorisation between March 23 and April 13, 2012.

Between those dates he also allegedly communicated or caused to be communicated the extracts to a third party without authority.

Mr Brough allegedly counselled and procured Mr Ashby to access and disclose the extracts and provide them to third parties without authority.

Karen Lynette Doane, who also worked for Mr Slipper, allegedly communicated or caused to be communicated extracts from the diary and provided them to third parties.
