The Geelong Refinery, an hour south west of Melbourne, Australia, caught on fire around 11pm local time (2pm BST) on Wednesday.

At least 10 emergency vehicles are currently at the scene tackling the blaze which is not yet under control.

The Country Fire Authority issued a watch and act for a large swathe of Geelong urging locals to take shelter indoors immediately.

“There is a factory fire in Refinery Road, Corio,” the advice said.

“A wind change has caused the smoke to be blown towards the Northern Geelong area.”

Residents were also being urged to keep off the roads to allow emergency services to respond.

The site is one of only two operational oil refineries in the country.

It supplies more than 50 per cent of Victoria’s fuel and around 10 per cent of Australia’s fuel.

It can process up to 120,00 barrels of oil a day, including “manufacturing petrol, diesel, LPG, jet fuel, avgas and Low Aromatic Fuel”.

It’s understood more than 1,100 people work at the site.
