The foster brother of slain Queensland schoolgirl Tiahleigh Palmer has applied for bail.
Trent Jordan Thorburn, 19, is charged with incest, perjury and attempting to pervert the course of justice over Tiahleigh's suspected murder.
Thorburn, who has been in custody since his arrest in September, lodged an application for bail in the Brisbane Supreme Court on Friday, which is set to be heard on December 14.
Corrections Minister Bill Byrne confirmed Thorburn had told guards he'd twice been bashed in jail by fellow prisoners only after the officers saw the second assault.

"The truth or otherwise of that is being established in an investigation," Mr Byrne said.
Tiahleigh was last seen alive on October 30 last year when she was dropped off at Marsden State High School, south of Brisbane.
A missing person alert was only issued six days later, hours before her body was found by three fishermen on the banks of the Pimpama River.
Her foster father Rick Thorburn, 56, was charged with her murder in September.
Foster mother Julene Thorburn, 54, and her son Josh, 20, last month pleaded guilty in the Beenleigh Magistrates Court to one count each of perjury and attempting to pervert the course of justice.
