Australian man dies in 'catastrophic' 200km/h crash

An Australian man has died in a fiery crash in Melbourne last night after a car slammed into his Mercedes at over 200km/h.

The suspected victim was a married 49-year-old father-of-one.

The crash was described by police to 7 News as "catastrophic in every sense of the word."

Both cars were on Waverley Road, East Melbourne, on Saturday around 2am when a Mazda hit the victim's Mercedes from behind at high speed.

The Mercedes burst into flames as it slammed into a street lamp, which snapped and fell on the road.

The Mazda struck another two cars outside a dealership before coming to a stop.

The driver of the Mazda, a man in his 30s, was cut from his vehicle and is in a serious condition in The Alfred Hospital. 

The police are investigating claims the man was driving erratically before striking the Mercedes, 7 News reports. 

He has yet to be questioned by police.
