A sex worker's cries for help while being held hostage by Brighton siege gunman Yacqub Khayre have been played to an inquest.
Khayre died in a police shootout after killing 36-year-old receptionist Kai Hoa at a serviced apartment in Melbourne on June 5, 2017.
The 29-year-old gunman also took a sex worker hostage and told triple-zero call takers he had a bomb.
"It's a hostage situation," Khayre said in the call played to Victoria's Coroners Court on Monday.
"The clerk is dead.
"There's a bomb in the premises as well."
The sex worker being held hostage can be heard saying: "Please help me". She survived.
Khayre was monitoring news of the siege while holed up in the apartment and called Channel 7, as he knew the network was covering it.
"This is the Brighton hostage," he said, according to a statement by the chief of staff at the time.
"This is for IS, this is for Al Qaeda."
Khayre had previously been acquitted of a terror offence and was on parole for unrelated crimes at the time.
He wore a GPS ankle bracelet to monitor compliance with his curfew.
In the lead-up to the siege, he committed burglaries to fund his purchase of firearms including a double-barrelled shotgun used in the siege.
Coroner Audrey Jamieson is examining the extent to which Khayre was being monitored on parole, and the extent to which his actions could have been anticipated and prevented.
