I'm not an expert on these two texts but you could consider the point of view first - In "Tracks", Robyn is choosing to move away from the settlements and any kind of familiar urban life and learning to be at ease in remote and desolate places. Charlie is at ease in his own place on the edge of a small town but is forced to confront the complexities of the urban environment when his health suffers and he's taken to hospital. I think the director also tries to be invisible to ensure that this is a 'genuine' (?) representation of indigenous experience, so there is a layering of the story - it's not just Charlie's experiences but how the director wants viewers to see that experience. In "Tracks", it's a bit more straightforward as Davidson tells her own story. So the landscape in "Tracks" seems like an alien place whereas in "Charlie's Country" it's the urban environment and the hospital (as well as rules and regulations, relationships with police) that seem really wierd and disorienting.
