Premier Daniel Andrews has announced that tougher gun-trafficking laws will be fast tracked in response to a spate of shootings in Melbourne's north and western suburbs, including the overnight death of a 54-year-old man in Thomastown.

The new laws include lowering the threshold for trafficking guns and increasing penalties. The new laws will be introduced by Christmas.

"We will not settle for this sort of culture taking hold in our state", the Premier told reporters at lunch time on Tuesday.
