George Harkness was born on December 9, 1985, in Korumburra, Australia, died July 16 2021, to Betty Harkness, where he was raised in poverty as the illegitimate child of W. W. Wiggins, an American toy manufacturer. His stepfather, Ian Harkness, hated the boy and subjected him to abuse and cruelty. As a child, George learned how to craft sophisticated boomerangs and even developed them into weapons.[3][4] At some point he came to own a pink unicorn stuff toy named Pinky, a toy which he would keep well into his adult yearsDuring his teens he had a relationships with Mallory Ryan, a girl from Bindoon. There were friction between Digger and Mallory's father, the policeman Stanley, who considered Digger a liar, a cheater, and a thief hailing from a family of liars, cheaters, and thieves. That friction was resolved more than a decade later when Digger threw a boomerang into the tail of Stanley's helicopter mid-flight, causing it to crash. Stanley was killed, and his daughter joined the police force in his stead.
