At McKinlay itself we found this delightful little building, the smallest library in Queensland. Maybe that makes it the smallest in Australia! Unfortunately it's only open on Thursdays so we couldn't go inside.
Although we didn't see any signs saying so (and there should be) just north of McKinlay we passed out of the Eyre catchment into the Gulf of Carpentaria catchment because now all the rivers are running north(ish) instead of south(ish). For most of our 3000 km trip north we have only been in two river catchments - the Murray Darling and the Eyre. Amazing when you think about it.
