Something Rotten in the State of Winsdor?

The Australian House of Representatives Standing Committee on Regional Australia's Inquiry into the impact of the Murray-Darling Basin Plan in Regional Australia is one strange entity.

Throwing process transparency to the wind, it is now selectively publishing copies of the 535 submissions received to date.

This is a snapshot example of what the list looked like on 17 January 2011 after the first 160 submissions:

So what is being hidden? Naive submissions of which there were already plenty in the first 160 received? A committee or secretariat in organizational disarray?
Or is it that the the Chair just doesn't want the bulk of the over 300 unpublished submissions out in the public arena before the mainstream media reports on the public hearings and the Committee delivers its findings?

It goes without saying that such questions would not even come to mind if submissions had been published in the order in which these were received and not as this highly selective hotch potch.
