                     DRILLING ACTIVITY UPDATE: CLIFF HEAD-6


Roc Oil (WA) Pty Limited, Operator for and on behalf of the WA-286-P Joint
Venture, advises that, as of 0600 hrs Australian Western Standard Time, the
Cliff Head-6 well ('CH-6') in the Cliff Head Oil Field in the offshore Perth
Basin, Western Australia, had been drilled to a Total Depth of 1,530 metres and
logging was is in progress.

Preliminary analysis of the log data received to date indicates that the well
has intersected a 71 metre vertical gross oil column with an oil-water contact
consistent with the field-wide contact. Net to gross is approximately 70%.
Porosities in the reservoir sequence are generally in the mid to high teens with
sections above 20% porosity. Because CH-6, located in the main horst part of the
field, has been drilled at an angle of approximately 40 degrees the gross
reservoir interval intersect by the well is 93 metres. The forward plan for CH-6
is to complete logging, run casing and suspend the well as a potential future
oil producer.

The Joint Venture plans to meet on 11 March 2005 to consider a Final Investment
Decision for the project.

The WA-286-P Joint Venture comprises:                         Equity
