Fire and Rescue NSW (FRNSW) investigators are working to determine the cause of a fire which has engulfed a factory at Jamisontown, in Sydney's west.
More than 40 firefighters and 14 fire trucks were deployed to the Regentville Street complex, where the blaze broke out just after 10 pm.
It had started in a unit used to manufacture perfumes and colognes.
Structural damage
Flames quickly reached high above the building, causing the roof to collapse and leaving behind significant structural damage.
Fire crews battled for several hours to contain and extinguish the fire, managing to save some neighboring units.
No injuries have been reported. Experts from FRNSW's Fire Investigation and Research Unit (FIRU) are working with NSW Police to establish what sparked the fire.
