The correct answer is nobody.
It is a common belief that Ned Kelly's last words before execution were "Such is life". Monash University Academic Dr. Stuart E. Dawson reports in the peer reviewed journal, " "Eras" reported:
"This is a key part of a prevalent Kelly mythology that has been subject to little serious critique. Yet the attribution of the phrase 'Such is life' to Kelly is pure fiction. Analysis of the reportage of the day reveals Kelly's actual last words, and
explains how they were transmuted by one journalist into the catchy expression quoted as fact by many historians. It shows that the image of Kelly standing tall and defiant, saying 'Such is life' as the rope was placed around his neck, is nothing but a highly romanticised myth. In fact, Kelly came to an ignominious, mumbling end on the scaffold, a far cry from
popular legend."
Ned Kelly's Last Words were "Ah, Well, I Suppose" .
