                      MAURITANIA OFFSHORE DRILLING UPDATE

ROC advises that the following release was made earlier today by Woodside
Petroleum Limited:

'Woodside Mauritania Pty Ltd, a wholly-owned subsidiary of Woodside Petroleum
Ltd., reports the following activity offshore Mauritania since the last report
issued on 23 November 2004.

                                 PSC-B, Block 4
                             Tiof-3 ST2 and Merou-1

Tiof-3 ST2 Appraisal well

The 'West Navigator' drill ship is preparing to suspend the Tiof-3 ST2 well as a
potential future development well. The production test data acquisition has been
limited to various samples and pressure measurements due to operational
difficulties. Further production testing of the reservoir will be required
during the appraisal campaign.

Merou-1 Exploration well

The 'Stena Tay' drilled the Merou-1 exploration well to a final total depth of
3,060 metres.

Evaluation of logs acquired while drilling and wireline logging operations,
including fluid sampling and downhole pressure measurements, has established
that the well intersected a number of thin gas and water bearing sands. Initial
interpretation suggests that the accumulations are sub-economic, but further
analysis will be required to determine the full significance of the well
results.

At midnight on 29 November the 'Stena Tay' was plugging and abandoning the well
as planned prior to moving to the Tiof-5 appraisal well location.

All reported drilling depths are referenced to the rig rotary table and all
times are Universal Time (UTC) (Mauritanian time).

The locations of the Chinguetti Oil Field, the Tiof and Banda discoveries and
exploration wells are shown on the attached map*.

Wells are expected to be drilled in two production sharing contract areas during
the remainder of the 2004/5 campaign.'
