Born into a poor working class family in turn-of-the-century Australia, Greg had a difficult childhood. He was often influenced by rowdy friends and left school early to work to support his family. Witnessing the discrimination faced by an Aboriginal boy in his community inspired Greg to start helping fight for black people's rights, though his friends disapproved. The story explores the hard life of the working class in early 1900s Australia through Greg's experiences growing up poor and having to take on responsibilities from a young age.
