Oliver Jordan Schulz is living at an undisclosed location in rural NSW, charged with unlawfully killing a civilian while deployed in Afghanistan in 2012.
The 41-year-old was granted bail on March 28 but conditions requiring him to report to the nearest police station each day have been complicated because of its irregular opening hours.
"The accused has been attending at different times and finding it unattended," crown prosecutor Talia Epstein said on Tuesday.
His bail was varied in Downing Centre Local Court allowing Schulz to attend the police station in person and, if it was closed, remotely connect to another nearby station to report without breaching his bail conditions.
Magistrate Susan Horan found any risks he would not appear in court were still addressed by the changes because he had to be physically present when reporting anyway.
Discussions are also ongoing between the Office of the Director of Public Prosecutions, Schulz's legal team and the Commonwealth Attorney-General about how the ex-SAS soldier can access his brief of evidence without breaching national security laws.
The matter will next come before the court on June 27 after Schulz and his lawyers have had time to consider these security concerns.
The soldier is accused of approaching Dad Mohammad in a wheat field in Uruzgan Province and then firing three shots at the a 25 or 26-year old while he was on his back with his hands and knees raised.
Mr Mohammad's father later made a complaint to the ADF, alleging his son had been shot in the head.
In March, Schulz was granted bail despite the seriousness of the alleged crime after a magistrate found he was at a high risk from Taliban attack if he remained behind bars.
Orders were also made barring the public from reporting the town and region where he resides to protect his family from retaliation by the Islamic fundamentalist group.
