Beaumont Lamarre-Condon is charged with two counts of murder after police found the bodies of Qantas flight attendant Luke Davies, 29, and TV presenter Jesse Baird, 26, in February.
The 29-year-old's Legal Aid lawyer Alex Curnick told Downing Centre Local Court on Tuesday she was seeking Cellebrite reports on her client's phone, a reference to software police use to extract data from mobile phones.
Data taken by police in Cellebrite extractions includes location information, internet browsing history, text messages and call logs.

The bodies of the two men were found on February 27 inside surfboard bags at the fence line of a rural property in Bungonia, near Goulburn, about 200km southwest of Sydney.
Lamarre-Condon is alleged to have shot them at Mr Baird's inner-city home with his service weapon before attempting to dispose of their bodies.
The court heard police did not oppose handing over Lamarre-Condon's phone records, but there were still some issues with revealing records tied to several others involved in the case.
"At the very least, I'm hoping in the meantime the Cellebrite from the accused's phones can be ... be served on us," Ms Curnick said.
Magistrate Greg Grogin said the documents should be produced for the court to rule on what was permissible to be produced.
"Documentation should be produced in the court and not withheld," he said.
"Let's get some documentation that can be produced for the defendant as and when it becomes available.
"Let's get this thing moving."

The former senior constable is facing two counts of domestic violence-related murder and one count of break and enter with intent to commit an indictable offence.
Police allege the attack was premeditated after a months-long campaign of "predatory behaviour" targeting Mr Baird, who Lamarre-Condon briefly dated before the TV presenter began a relationship with Mr Davies.
Suspicions were raised after possessions belonging to the men were found in a skip bin in the southern Sydney suburb of Cronulla, leading police to Mr Baird's blood-smeared share house in Paddington.
Lamarre-Condon was sacked by the NSW Police Force in mid-March.
He joined the force in 2019 and previously ran a celebrity blog, posing in photos with dozens of A-listers including Taylor Swift, Selena Gomez, Katy Perry, Miley Cyrus and Harry Styles.
The matter will return to court on Feburary 28.
