Australia has various forms of Management, including Receivership, Liquidation, Deed of Arrangement etc., some of which would have (and did) permit the company to continue trading.
A Receiver/Liquidator has an obligation to investigate the affairs of the company. It's interesting that the Liquidator does not appear to have confirmed or denied allegations involving missing engines, fuel accounts etc.
A prominent politician once said to me "Never hold an inquiry unless you first know the outcome." I guess you'll never see an inquiry into Ansett.
