Progress Report on Fiddich 1, Offshore Perth Basin, Western Australia

ROC advises that the following release was made earlier today by Origin Energy
Limited:

'Origin Energy Limited, as Operator of offshore Perth Basin Exploration Permit
WA-226-P, advises that at 06:00 hours WST the exploration well Fiddich-1 was
drilling ahead in 216 mm (8 1/2 inch) hole at a depth of 1258 metres.

The well intersected the primary target at 1232.5 metres. Logging while drilling
and the absence of significant hydrocarbon shows during drilling indicate that
the primary objective is water bearing. The well will now be drilled to TD
before a decision is made on whether wireline logs are run.

Apache Energy is managing the drilling of the Fiddich 1 well as agent on behalf
of Origin Energy.
