Ozbiggles... in a nutshell:
The panel did not find enough documents to verify that the actions of Flt Lt Cooper occurred, and therefore did not recommend any Imperial awards - this is despite the American recommending him for various awards (incl the Gongressional Medal Of Honour and the Air Force Star which he couldn't receive because he was not a member of the US armed forces but was only 'attached' to them ie he was RAAF personnel) - as far as I understand, he got a Bronze Star.
The statement of Flt Lt Cooper in the report is well worth reading - especially when comparing ADF 'record keeping' as compared to US armed forces 'record keeping'.
It's a pity this nation hasn't officially recognised and rewarded the gallant acts and significant contribution as a warrior by Flt Lt Garry Cooper.
