Immigration Nation is an ambitious three part series telling the secret history of how modern multicultural Australia was forged against the odds. More than simply a social history of different migrant groups it is a dramatic political thriller based on interviews with eminent historians and the testimony of eyewitnesses - many of whom have never told their stories before - to the momentous events that built a nation. This is combined with rarely seen archive, specially shot sequences and cutting edge computer graphics applied to the actual places the events unfolded - both at home and overseas.
