Banished, like many other series in this genre, is a fictional drama set during an historical period. Which is 1788, and the establishing of a penal colony by the First Fleet in NSW Australia. I am not all that knowledgeable on the settling of NSW but, from the first episode it it didn't appear to be historically accurate nor did I really expect it to be. That being said, I did enjoy the series. Further reading into the settling of NSW, it would have been more interesting if the writers used the accounts of the settling of NSW.
