A Queensland man has been accused of tying up a woman he knew and threatening to set her alight during a 14-hour ordeal in which she was also raped and tortured.
Police say the 29-year-old will spend days in hospital after the attack, which also saw her doused in petrol.
The 31-year-old man accused of the horrifying assault is also in hospital after he was stabbed in the side.
The woman voluntarily went to a Maroochydore home on Wednesday night but was not allowed to leave, police allege.
She was held and attacked over 14 hours before being able to make a panicked call to friends on Thursday morning, pleading for help.
They rushed to the house as a domestic cleaner who'd showed up for work was also on the phone to police, telling officers something bad was happening.
"Police will allege part of those assaults included the woman having petrol poured over her and threatened to being set alight as well as being assaulted with objects," Detective Sergeant Chris Eaton told reporters on Friday.
"From there, the female victim was able to use a telephone yesterday morning whilst the offender was distracted.
"She was able to call friends who subsequently attended at the address. It was at the address at that time that the male person has sustained the stab wound and police are investigating that particular matter."
The woman's alleged attacker was previously known to police. The woman also knew him but they were not in a relationship.
"The female victim is still in hospital. Her injuries are non life-threatening but they are serious injuries," Det Sgt Eaton said.
"It would have been terrifying for the victim. We will allege she was tied up for a protracted period of that time."
The man's stab wound is not life threatening. Police have interviewed the friends who went to the woman's aid.
"A number of people were spoken to yesterday ... At this stage no-one has been charged in relation to the stab wound to the male offender."
The man has been charged with rape, torture, deprivation of liberty, acts intended to cause grievous bodily harm and assault occasioning bodily harm.
He faced a bedside hearing on while in hospital on Friday.
The case was adjourned to July 19 for a committal mention at Maroochydore Magistrates Court.
