Have a look at these charts of coal prices in $AUS & $USD
That surely has to mean something, to someone.
Correct me if I'm wrong but revenue of $26,484Mil divided by coal sold for the half year (408,595) = $64.81/ton sell price. Right?
Unless there was another source of revenue which I don't think there is (ie draw down from overdraft) I'm not an accountant lol.
