On a similar note to the McCubbins, Shearer in Red Shirt from Shearing the Rams.

Part of me wants to say that if you're going to have a Banjo Paterson character, there should also be a Henry Lawson character, but he didn't tend to go in for the kind of larger-than-life characters who would be suitable. The only thing coming to mind that might work is "The Loaded Dog", and a romance path inspired by that would be exciting but probably rather short.
