It is the 1860s and colonial Australia is no longer just a dumping ground for the pitiful throw-offs of harsh English justice. This cruel system has sent thousands off to the penal colony for the pettiest of crimes, and few will ever see their homeland again. The colony is rapidly taking on a new identity as a land of vast resources where land and opportunities abound for those who are up to the challenge. Into this wild land of rare beauty and constant change comes a quiet young orphan boy named Brennan. He knows nothing of his origins and his only family is an old lady who nurtures him into his teenage years. When she can no longer care for him, he packs a modest swag and a little money and heads into the bush. On the track, he meets up with two old swagmen who quickly become his new family. Tramping the bush tracks around the brooding land of a million contrasts, they find many adventures. Set against the backdrop of the beautiful bush, they experience bushfires, floods, droughts, harsh winters, blistering summers, and the kindness and sometimes cruelty of the inhabitants. This story provides an insight into early Australian colonial history, the land, and its people, as seen through the eyes of a mystical young swagman.
