                     DRILLING ACTIVITY UPDATE: CLIFF HEAD-6


Roc Oil (WA) Pty Limited, Operator for and on behalf of the WA-286-P Joint
Venture, advised that the Cliff Head-6 well ('CH-6') was drilled to a depth of
1,368 metres measured depth on 5 March 2005 at which time coring operations were
commenced. The preliminary estimate of top of the reservoir has been interpreted
to be at 1,373 metres measured depth, based on shows, providing a gross vertical
reservoir section of approximately 70 metres above the field wide oil water
contact. The reservoir section will be better defined by open hole logging which
is planned for the well after coring has been completed and the well has been
drilled to the planned total depth of 1,497 metres.

The current operation on CH-6 at 0600 on 7 March 2005 was preparing to cut core
#3 at a depth of 1,400 metres.
