The man accused of murdering his stepdaughter Charlise Mutten has asked to be kept away from other prisoners while in custody over the alleged killing.
The body of nine-year-old Charlise was found in a barrel on Tuesday night in scrub near the Colo River - an hour from where she disappeared on a private property in Mount Wilson, in NSW's Blue Mountains.
Justin Stein, 31, appeared in Central Local Court on Wednesday morning where he did not apply for bail and it was formally refused.
His barrister told Magistrate Robert Williams his client needed his medication for mental health issues while in custody, adding he had been on 'high dosages' for many years.
He also expressed Stein had concerns for his safety.
'The other matter I'm instructed to raise relates to his concerns for personal safety in custody,' the barrister said.
'He has asked the court to recommend a no association classification.'
Magistrate Williams said Corrective Services NSW only had the power to separate the accused from other prisoners.
Stein's lawyer also asked the court for a 12 week adjournment to seek a mental health assessment, noting his 'long term medication'.
It comes after police alleged Stein drove around Sydney for hours with his fiancé's daughter's body in the back of a boat while he tried to figure out where to dump her, the Daily Telegraph reports.
It is understood detectives believe Charlise's mother Kallista Mutten had left her daughter in the care of Stein last Tuesday night - the last time she was confirmed to be alive.
Police will allege she was killed within the following 15 hours.
Charlise Mutten, 9, was initially believed to have last been seen on Thursday but was reported missing on Friday morning. Police will now allege she was killed on the Tuesday night, three days before her mother called 000

Homicide detectives retraced Stein's steps using CCTV after he allegedly bought five 20kg sandbags from Bunnings, fuelled up a boat, then tried to launch it from an inner-Sydney dock.
After finding the boat was inoperable, police will allege he then tried to dump the barrel containing Charlise's body in Colo River but was unable to roll it in due to the weight of the sandbags.
It is alleged he instead left her in bushland, where she was later discovered.
A blue tarpaulin was also found in the back of the boat. The barrel has now been seized and will be forensically examined.
Police revealed in a press conference on Wednesday they will allege Stein discussed buying sandbags and boat fuel before later travelling to the riverbed where his stepdaughter's body was later found.
The accused appeared in Central Local Court on Wednesday from Surry Hills police station, where he is detained
'(There were) a number of telephone conversations, to purchase a number of sandbags,' Deputy Police Commissioner David Hudson said.

He wore a grey Everlast jumper and shorts which he was still dressed in when he fronted court on Wednesday morning.
