Ann: Gas Sales Agreements Executed with Australia Pacific LNG, page-9

Kind of difficult to know as dollar numbers weren't mentioned in the announcement.
To me it looks like 1.8PJ for a fixed price for fixed period (minimum 5 years), however the announcement spoke of 3.6PJ with nothing mentioned of the terms of the rest. A starting point would be current wholesale prices p/GJ somewhere above $5 (less costs) but possibly much more. 1PJ = 1million GJ.
What it does give us is some stable income to work by. I'm thinking some actual figures, along with updated info, might be in the Quarterly end of this month.
