I double checked, you're right on the $2.7m being for 'one off' legal fee's, so I was mistaken in the ARU using it for the new entity. BUT, the other costs still apply of what cutting the force means on the advice given to the ARU both in removing the force and dealing with SANZAAR.
In terms of the print bundle cost. Yeah sorry, but that $500 doesn't even cover the time charged by external parties to print (which CU use as a FYI).
I'm not too sure if you're serious about why you would brief a SC + Junior for 'one day'. The ARU were clearly going to fight it in court if they lost arbitration. For an event that lasted 6-8 months (the ARU would have engaged CU before announcing the cut), that $2.7 with all costs considered is pretty 'reasonable'.
