The Castle is a must see. Iconic feel good movie. There are Australian sayings in there only us locals in Victoria would properly understand, as it is based here. I am not sure if foreigners would understand it fully; but a great low budget film all the same.
A excellent series now on Netflix is Stateless. I started watching it last night at around 8pm and got hooked. Finished the whole series by 2am. Based on a true story of imprisonment of asylum seekers here by an incompetent federal government, although it is worth checking out the facts by Googling "Cornelia Rau" after seeing the movie. Vivian Solon was also a victim of federal government ineptitude but she is not mentioned in the movie... that would be another movie all on its own.
