CCTV has emerged of a 12-tonne front-loader tractor being used to smash into a Melbourne supermarket and steal cash.

The footage shows the vehicle ramming through the double-glass doors of the McDonald’s Road shopping complex in South Morang about 1.20am today.

Reversing and accelerating several times into two ATMs, the vehicle picks up what appears to be a safe dislodged from inside.

A man wearing a hooded fluro jumper can be briefly seen before the robbery ends in less than three minutes.

It remains unclear how much cash was stolen, with the safe inside the Bank of Melbourne teller machine missing.

The safe inside the other ATM from the Commonwealth Bank remained in the supermarket.

Local MP Craig Ondarachie told 9NEWS he believes the crime was pre-meditated.

“Someone has planned this out. This is the fastest growing shopping centre in Melbourne, there’s a lot of construction around here.”

The front-end loader was stolen from a nearby concreting business shortly before the ram-raid.

The owner of the tractor said he was shocked that it had been used in such a damaging crime.

“It's just unfortunate that we were the target…we would assume they maybe hot-wired it, had some kind of a key… who knows,” Paul Camelleri said.
