Today, the Brisbane Magistrates Court heard Mr Wardle was being held in a mental health ward and would not face court until Thursday.

A fundraiser set up by a family member of the young couple, shared by Mr Beaumont, said they "had only just moved out of home for the first time"

"The home they had only just started building together was turned upside down through no fault of their own," a relative of the couple wrote.
