Flinders ands Urrbrea aren't a million miles from each other in the grand scheme of things. I agree with Snifter that the South East, around Mylor and surrounding areas, would be a good place to look. If you go on to realestate.com.au and search for acreage in Mylor and surrounding suburbs quite a few places come up. I've been having a quick look and found a place that looks ideal, with veggie gardens and a chicken shed. I would post a link but I was looking on the app on the iPad and not sure if I can link from that.
