A tradesman sick of having his tools stolen from his work vehicle has turned to bumper stickers to humiliate potential thieves.
The scathing message, which was attached to the front of his trailer, is meant to make criminals think twice about taking what isn't there.
"Don't steal my tools, I need them to pay for your benefits," the sign reads.
The image was taken by a Melbourne road user, who posted it on Facebook.
It has since gone viral after a resident sent the image into the Sunrise TV show.
