Defence lawyers for Lloyd Rayney, the Perth barrister accused of murdering his wife, are seeking information about police investigations into "other suspects and persons of interest" in the matter, a court was told this morning told.

The Supreme Court was also told that the former State prosecutor's trial was expected to begin around June next year.

Mr Rayney has pleaded not guilty to the alleged murder of Supreme Court registrar Corryn Rayney in August 2007, with the mother of two's body found buried in Kings Park days after she went missing from a dance class.

Today, defence lawyers for Mr Rayney told the Supreme Court that they were waiting for certain materials to be provided to them by prosecutors.

The material being sought included information about other suspects and persons of interest that were investigated by police in the murder case.

Defence counsel David Edwardson said a number of people had been clearly identified as "persons of interest and potential suspects" in the case.

He said his team wanted full disclosure of the extent of police investigations into those people, describing the material as "fundamental" to Mr Rayney's case.

The defence team was also seeking material relating to expert witnesses and reports.

Counsel John Agius, for the State, told the court that only one expert report outstanding, which had not been commissioned by prosecutors in the murder case.

Mr Agius told the court that the State had fulfilled all its disclosure requirements.

He said his understanding was that defence lawyers had visited police two weeks ago seeking profiles and documents regarding four people in the murder investigation.

Mr Agius said the lawyers had viewed the documents and been told they could make a request for copies of the documents in writing - a written request that Mr Agius understood had still not been received.

Mr Rayney will next appear in the court on October 13. His bail was extended.

Outside court, his instructing solicitor Laura Timpano said: "As you are all aware this case is attracting a lot of publicity and media attention and the defence team as a whole are very grateful to the court for taking all appropriate steps to ensure that there will be a fair trial in this matter and the defence team are looking forward to it."
