Police fear Porsche driver Richard Pusey has a series of graphic photos of the horror Eastern Freeway crash that killed four officers stored on devices they cannot access.
A magistrate denied his release on bail on Monday in part because they can't access his password protected phone and tablets.
Pusey, who uses they/them pronouns, is facing two charges of using a carriage service to harass over the alleged posting of images from the April 2020 crash online.
They're also accused of committing offences while on bail.
It's alleged they attached an image to an email to the Australian Financial Complaints authority in December last year.
They are also accused of posting an image to a review on the home page of Porsche Centre Melbourne, a car dealership in Collingwood.
Prosecutors say their case is strong because Pusey's personal details including name, address, email and phone number were included in the AFCA email and their insurance policy was referenced in the dealership review.
Police were opposed to Pusey's release, telling Sunshine Magistrates Court the release of images from the crash caused widespread distress to individuals and families.
Officers have to go through Apple in the United States to access Pusey's iCloud account because they cannot access password protected devices, a process which is proving problematic, the court heard.
They said there is an unacceptable risk of reoffending if Pusey has access to the images, which have been posted publicly in the past.
Pusey self-represented in the bail application arguing they had been unable to properly defend their matter while in prison.
The videolink to Metropolitan Remand Centre was late starting on Monday.
"These meetings are always cut short - this morning I lost 15 or 20 minutes because the system doesn't work," they said after bail was denied.
Magistrate Michelle Mykytowycz acknowledged their concerns.
Pusey's access to phones and the prison library has been reduced because of COVID-19, she said.
They are also unable to photocopy documents or view electronic material including their police interview and body-worn-camera footage while in custody.
Pusey also said they have to fight to be given their weekly prescription medication even once a month.
Ms Mykytowycz wasn't satisfied by Pusey's argument that they would spend more time in custody because of delays than if they were found guilty.
If convicted, Pusey faces 12 months behind bars on each charge.
