I personally wouldn't have any qualms with the area circled in red being officially named the Wylly Plateau. After all, many of us already refer to it as that (thanks to Chapman's books), plus it does fit the geographical definition of a 'plateau', it is in close proximity to Mt Wylly (hence the use of the same name), and it's one of the more popular places to camp on the Southern Ranges, so would seem logical to give it a name.
That's just one idea though. I'm curious to see what geographical features everyone else thinks should be given a name of sort.
