Indeed dxhound2003. My Wikipedia confirms that Mount Augustus is a monocline, but also states it is the world's largest monolith!
Mount Augustus has a central ridge which is almost 8 km long, and is the world's largest monolith.
And Uluru is an inselberg, literally "island mountain", an isolated remnant left after the slow erosion of an original mountain range. Uluru is also often referred to as a monolith, although this is a somewhat ambiguous term that is generally avoided by geologists.
