The 47-year-old was arrested in April and charged with murdering or ordering the murders of five unarmed detainees while deployed in Afghanistan between 2009 and 2012.
The Victoria Cross recipient is living with his partner in a property owned by her parents, who have just sold their home and are intending to move into the house in which Roberts-Smith now resides.
As a result, he is looking to lease a new residence in southeast Queensland for himself and his family, prompting his lawyers to request a change to his bail conditions at Sydney's Downing Centre Local Court on Tuesday.
"It's a chicken and an egg situation," Judge Susan Horan noted.
"He wants to understand the position of the court before he goes and secures accommodation, and I appreciate that."
The judge found it was appropriate for Roberts-Smith to move house once his new address has been provided and checked by the director of public prosecutions.
She also changed his reporting requirements to avoid forcing him to make a three-hour round trip to a NSW police station three times a week.
Roberts-Smith will be asked to report to that same police station just once a week and report twice weekly to a station in southeast Queensland.
In mid-June, the ex-soldier had his bail varied, allowing him to attend the opening of ANZAC Hall at the Australian War Memorial in Canberra on Tuesday evening.
However, his barrister Slade Howell told the court his plans had changed.
"Mr Roberts-Smith fell ill in the last couple of days and hasn't travelled to Canberra today to attend the official opening at the War Memorial," he said.
Roberts-Smith has not entered pleas to any of the charges but has said he will use the upcoming trial to clear his name.
Australia's most decorated living soldier is accused of machine-gunning Afghan prisoner Mohammed Essa and ordering the execution of his son Ahmadullah to "blood the rookie" during a raid at a compound in April 2009.
The then-SAS soldier allegedly placed firearms on the bodies to falsely claim they were enemy combatants, court documents said.
In August 2012, at the village of Darwan, Roberts-Smith is accused of kicking a handcuffed man named Ali Jan off a 10-metre cliff before ordering that he be dragged to a creek bed and shot.
Two months later at Syahchow, he allegedly lined up two prisoners in a corn field before shooting one of them with another soldier.
He ordered a subordinate to shoot the other prisoner before throwing a grenade on the bodies to cover up what he had done, prosecutors allege.
