Most of the questions for Distinctively Visual are about the ways in which composers take us to other worlds/new experiences or challenge us/develop our thinking about experiences using distinctively visual techniques. The related texts you choose do not have to be about the same ideas/experiences as your prescribed text-i.e. 19th century rural Australia-but they should have some depth to them that you can discuss regarding their ideas and the visual ways that those ideas are shown to responders. If you feel more comfortable choosing Australian texts set in that period then poems by AB Paterson might help-"Man from Snowy River", "Ballad of the Drover" etc. Films about Australia from the past include "Australia" (Kidman, Jackman) and "My Brilliant Career".
There are some excellent picture books which depict conflict/division in society, like Marsden/Tan's "The Rabbits" and a terrific new one based on the song, "I was only 19" which allow you to analyse a few openings, looking at colour, size, perspective, salient features, expressions/body language. A poem by Bruce Dawe (contemporary Aussie poet) called "Up the Wall" talks about loneliness and isolation for the modern Australian housewife and there are several good poems about drought in the Australian outback. "Crocodile Dundee" gives us the type of character that Lawson is talking about in some of his stories-tough, slow speaking, good sense of humour, resilient that you could link to Lawson. Choose a couple of scenes to examine in detail-the way camera shots, music, lighting, editing and any other distinctive/special features help to demonstrate the experiences of the main character which support the ways in which Lawson demonstrates his characters and ideas. Hope this starts you thinking about a few texts of your own. All the best.
