Geologically speaking there is a (significant) difference between a monocline and an asymmetric anticline (which is how the Geol Survey of WA describe it I believe). Haven't seen the geological map of the area but I'd be interested to see what fold symbol was used to depict the structure. Have a look at p19 (13) of this Geoscience Australia PDF if you are really interested in geol folds:

Whether Mt Augustus can be decribed (accurately) as a monolith is a moot point though, I'll grant you that (a monolith being a single big lump of rock, so to speak). Geologically speaking, it ain't, but from a layman's point of view he might reasonably call it one. As to the claim that it is the world's biggest monolith,
well let's just say that it has a nice ring to it.
