Three people have died in a house fire that tore through a home in Sydney's southwest. Emergency services were called to a Cornelia Street property in Wiley Park around 9:45 p.m. on Wednesday, July 29, 2026, following reports of a fire.

Upon arrival, twenty firefighters encountered a significant blaze. A statement from Fire and Rescue NSW (FRNSW) indicated that crews forced their way through the burning exterior of the property to extinguish flames that had spread to scaffolding and garden trellis.

The bodies of three individuals were found inside a granny flat located at the rear of the badly damaged home. The victims have not yet been formally identified. Police have established a crime scene and launched an investigation into the cause of the fire.

"Our investigators will examine the scene thoroughly, once it's been declared safe," FRNSW Commissioner Jeremy Fewtrell stated. "We offer our condolences to the families of the victims of this terrible tragedy. This is a stark reminder of the dangers of home fires, particularly during the winter period."

A report will be prepared for the coroner. Authorities are urging anyone with information about the fire to contact Crime Stoppers.
