No idea, but they've always reported boe.
2TJ/day = 180TJ for qtr = 30k boe (from gas)
140k boe (from oil)
If you know the average oil price over the 3 months - $100 AUD
You can reverse engineer the implied JCC price that gives you $87AUD weighted average.
This will give you a rough idea.
To be more exact you would need to factor the hedge...
