In short...definitely YES! In Australia, good one word names and two/three word exact match domains in .com.au can go for surprising high amounts. One word .au names are also starting to take off. The fact that global domainers cannot purchase .au names has not bearing on what Australian end users are willing to pay for the domains. I've been told by some Australian domain veterans that certain 3L .com.au's go for the same price as 3L .com's, which is crazy, but happens. I personally sold a .com.au yesterday for AUD22,000 - which is rare, but shows that it's possible.
