80 firefighters were deployed to a building in Melbourne’s Spencer Street on Monday morning to battle a blaze that has prompted fresh concerns about combustible cladding on apartment buildings.

The fire began shortly before 6am and shot up several floors of the apartment complex, prompting the Metropolitan Fire Brigade to upgrade the emergency.

Dan Stephens, chief officer for the Metropolitan Fire Brigade, says crews believed the building was clad in the same material as the Grenfell Tower in London, which caught fire in 2017 and killed 72 people.
