An abandoned five-year-old English boy, Leon, is rescued by a compassionate neighbouring family who adopt Leon and move with him to Australia for a better life in 1903.
Rocky, a relative of the family already in Australia, allows them to reside in his majestic country homestead, near Wangaratta in Victoria. Rocky clearly has considerable wealth, though it soon becomes clear he didn't earn it through hard work.
Leon embraces farming and rural life in the wild colony, but unbeknown to him, he is being groomed for bigger, murkier things.
When two men are murdered on a remote cattle station, Rocky, Leon and Adam, an aboriginal man, go in search of the killer. In the process they become embroiled in cattle theft, fraud and more death.
Wonnangatta is a sweeping saga of mystery, romance and intrigue played out against the raw beauty of the Australian bush.
