Some people will go to great lengths to get hold of a Bunnings sausage in bread.

A man who only wants to be known as "Tim" has admitted he was part of a team that flew a drone to pick up a sausage from Bunnings and deliver it to a friend waiting in an outdoor spa in Sunbury.

Tim says it was all a bit of fun.

But the Civil Aviation Safety Authority is investigating the incident after a video was uploaded to YouTube showing a man piloting a drone to the Sunbury Bunnings carpark while he sat at his home.
