Zdravko Bilic, 57, was found dead with stab wounds in the yard of his beachside home by a neighbour at Queensland's Sunshine Coast on July 14.
Days after police charged boys aged 15 and 17 with his murder, a young woman was arrested on Tuesday at Toowoomba nearly three hours' drive from the alleged crime scene.
Kieysha Jade Sky, 18, was not required to appear in Toowoomba Magistrates Court on Wednesday when her charge of murder was first mentioned.
Sky, from Logan suburb Bethania, south of Brisbane, was also charged with assault occasioning bodily harm, armed robbery and two counts each of motor vehicle theft and break-ins along with three attempted break-ins.
Defence solicitor Brad Skuse requested magistrate Michelle Dooley transfer the matter to Maroochydore on the Sunshine Coast.
Mr Bilic was found dead at the beachside home he shared with his wife, multimillion-dollar skincare business founder Gry Tomte.
Ms Tomte was not home at the time and had asked a neighbour to check on her husband after she had not heard from him.
Mr Bilic - a popular community member who worked as a junior soccer coach - was discovered by the neighbour about 7.30pm on July 14.
His death shattered the quiet suburb of Warana, which has rallied around his wife.
"He was loved by more people that I can put into words," Ms Tomte said in a statement released by Queensland Police.
"If you've had the privilege of being in Zed's presence, you'll know that he was literal sunshine ... and the world is a little less bright without him in it."
Police allege Mr Bilic was stabbed twice in an altercation with intruders after they allegedly entered the home about 11.30pm on July 13.
Ms Dooley on Wednesday ordered that Sky be remanded in custody ahead of the case being mentioned again at Maroochydore Magistrates Court on September 29.
Prosecutors were ordered to provide Mr Skuse with a brief of evidence in his client's case by September 3.
Sky's two juvenile co-accused were previously remanded in custody for a Maroochydore committal mention on September 10.
If convicted of murder, the boys will serve mandatory life sentences under the Queensland government's controversial "adult crime, adult time" laws, which came into effect in late 2024.
