WA's Supreme Court has been forced to take unprecedented measures to shield the public from graphic evidence in the Claremont serial killings trial relating to the burial sites of Jane Rimmer and Ciara Glennon, following a plea from Ms Glennon's father.

Former Telstra technician Bradley Robert Edwards, 51, is charged with the wilful murders of Ms Rimmer, Ms Glennon and Sarah Spiers in 1996 and 1997, but Monday's hearing — the first following a two-week break over Christmas — ran for less than 30 minutes before it was adjourned.

State prosecutor Carmel Barbagallo SC told the court the Rimmer and Glennon families had expressed concern about the evidence to be presented relating to the discovery of their bodies.

This included a large number of photos and videos from the burial sites where they had been found — in Wellard, in Perth's south, in the case of Ms Rimmer, and in Eglinton, north of the city, in the case of Ms Glennon — as well as of the post-mortem examinations conducted on the women's bodies.

The court had already been warned of the "particularly graphic and disturbing" evidence in pre-trial hearings and Justice Stephen Hall cited this as one of the reasons the trial would be heard by a judge alone, instead of a jury.

Ms Barbagallo said Ms Glennon's father, Denis Glennon, was so concerned about the possible public dissemination of the "distressing" images, he had written a letter to the court outlining why it should not be seen.

Justice Hall said while he had no intention of releasing the photos or video footage to the media, he wanted to drastically limit the number of people able to view it.

"In my view it is not necessary for anyone other than counsel and myself to be able to see it," he said, adding that while the material would be distressing for anyone to see, it would be "deeply distressing" for the families and this would be compounded by other people seeing it unnecessarily.

Screens a 'necessary evil'

Justice Hall said he wanted to avoid closing the court if possible because "justice needs to be done and needs to be seen to be done".

Ms Barbagallo proposed erecting masonite screens behind the legal benches and in front of the media section and public gallery, so that only the legal teams, the judge and those giving evidence could see the disturbing images.

Defence counsel Paul Yovich SC warned the screens would be "cumbersome" but a "necessary evil".

When Justice Hall said the court would be unable to provide the resources for the job because most of the staff were still on holiday, Ms Barbagallo said the prosecution would organise the arrangements, but warned it could take some time.

"I haven't been to Bunnings in the last little while," she said, adding that all of the necessary materials may not be available in the one store.

Four large white partitions were in place when the court resumed, forming a barrier between the senior legal counsel, Justice Hall and those in the witness box on one side, and the junior lawyers, detectives, the public gallery and the media benches on the other.

Edwards could see all the evidence being shown.

Not all of the exhibits were blocked from public view, with the court shown photographs of Ms Rimmer's Wembley flat and her silver Mazda sedan parked outside.

The neatly kept one-bedroom flat had pictures of Elvis and Marilyn Monroe on its brick walls and a blue plush teddy bear on Ms Rimmer's double bed.

First police to arrive describe Rimmer crime scene

Details of Ms Rimmer's burial site were also relayed to the court by a series of police officers, who described it as being located amid dense vegetation and not visible from the road.

Bleddyn Davies, then a junior constable at Kwinana Police Station, said he arrived at the scene with Senior Constable Michelle Beaman and saw a "white waxy lump" amid the bushes.

Senior Constable Beaman said the body "appeared naked, lying face down in the scrub" and was "in a decomposed state".

Possible contamination of Ms Rimmer's burial site was raised several times by the defence team as the witnesses were cross-examined by lawyer Genevieve Cleary.

She asked them detailed questions about what they were wearing and the police vehicle they drove, and both officers said they had been wearing standard issue blue police shirts and navy trousers with black shoes.

The discovery of blue polyester fibres in Ms Rimmer's hair is one of the crucial pieces of evidence in the case, with the prosecution set to argue they could only have come from Telstra work uniforms manufactured specifically for the company in the mid 1990s and worn by Edwards at the time.

The trial continues.
