In recent times I have noticed a quite remarkable increase in interest in the New England New State Movement. Half of the ten most recent searches have been on this topic.
To IP 58...., Mr Whitlam was a member of the Federal Parliamentary Constitutional Review Committee with David Drummond. This Committee recommended changes to the constitution to make the creation of new states easier. In regard to your second search on the New England Movement I have a fair bit of material covering the whole movement from the early colonial period.
The same advice applies to IP c211-30... who was also searching on the New England Movement.
To IP c211-30... who was searching on the Cohen Royal Commission, I can give you the full history here.
More broadly, my own support for separation will be clear from this blog. However, that does not prevent me supplying objective historical information. If you have questions or want info as to sources, please leave a comment.
Thinking about it further, perhps the most useful thing that I might do is to put up some more historical material on the New England history blog. I have been slow in posting material to this blog because of the time pressures on me, so far really only starting to sketch out a blog structure.
I will add a further postscript when I have put something up.
