A 'blueblood' society for the Antipodes?

Although I have a longstanding interest in genealogy for less purposeful reasons, some people's interests in this field are motivated by the desire to join one of the following "blueblood" societies: the United Empire Loyalists' Association of Canada, the National Society of The Colonial Dames of America, the Daughters of the American Revolution, the Sons of Confederate Veterans, and the United Daughters of the Confederacy. Membership in such societies is undoubtedly a satisfying experience for those able to prove prestigious ancestral connections. However, I rather like the idea behind this website: Convicts to Australia: A Guide to Researching Your Convict Ancestors. Makes you wonder what sort of societies might spring up down under from this research.
