It’s because legally, it’s part of a single Local Government Area. The same could be said of the Sunshine Coast, which contains 6 different sub-regions according to Wikipedia, and frankly I think that’s cutting it short (I count roughly 10 distinct towns). And, though it’s not included on this map (presumably because it’s considered part of “Greater Brisbane”) Moreton Bay City has at least 3 distinct areas (Redcliffe/North Lakes, Pine Rivers/Strathpine, Caboolture. And each of those slashes could almost be separated too).
