A major fire has ripped through a disused factory in Eastern Creek only metres from the M4.
Up to 120 firefighters from the NSW Fire Service and 80 firefighters from the Rural fire service are battling the blaze.

Smoke is billowing from the building on Peter Brock Drive in Sydney's west, which is believed to have collapsed during a hail storm in April.
Up to 90 people have been evacuated from nearby factories.
Rescuers do not believe anyone is inside the collapsed building, and there have been no reports of injuries.

The fire had been contained to the site by 5.30pm (AEST), but is expected to burn through the night.
Black smoke could still be seen kilometres away.
The cause of the blaze is unknown, a spokesperson for NSW Fire and Rescue said.
"We'll be here all night," said NSW Fire and Rescue Superintendent Ian Crimmer.
"We are slowly getting the upper hand."
The building had previously stored Hyundai spare parts.
"It still contains a number of chemicals related to the motor vehicle industry, fuels ... producing an enormous amount of thick black smoke," Superintendent Crimmer said.
Hazmat crews are monitoring the smoke plume.

Access to water was difficult for the firefighters and multiple crews were called in to assist.
Aerial footage from news helicopters shows the collapsed roof of the Mobis Parts Australia factory building is engulfed in flames.
The smoke is billowing away from the M4, but traffic is very heavy along the motorway, especially westbound near Reservoir Road due to the fire.
Motorists have been told to expect significant delays during peak hour.

NSW Fire and Rescue have asked drivers on the M4 to take care and wind up their windows.
"It's probably tempting to do a bit of rubber-necking, but we don't want anyone to be in an accident," a spokeswoman for NSW Fire and Rescue said.
