I think weekly reporting would just add to the costs of the administration and would be of little value. The Administrators would likely have meetings with the Committee of Creditors they established and the minutes of such meetings should be available on ASIC (or hopefully the Administrators' website) after they are held.
Possibly the only avenue available for shareholders to get money back would be finding evidence that the IPO disclosures were inadequate and suing for compensation (though this would only be viable for those who bought through the IPO I would imagine).
