| MAURITANIA OFFSHORE DRILLING UPDATE: (27-09-2005) |
Woodside Mauritania Pty. Ltd., a wholly-owned subsidiary of Woodside Petroleum Ltd., reports the following activity offshore Mauritania since the last report issued on 20 September 2005.
PSC Area B: Tevét-2 Combined Appraisal and Exploration Well The ‘Stena Tay’ rig drilled the Tevét-2 well to a depth of 2,785 metres. Wireline logs, including fluid sampling and downhole pressure measurements, were acquired over the Miocene appraisal objective, where oil and gas was discovered in the Tevét-1 well. A preliminary evaluation of these data and data acquired while drilling has established that the well intersected a gross gas interval of approximately 1.5 metres above a gross oil interval of approximately 37 metres. Whilst the hydrocarbon sands are of a similar thickness to those discovered in the Tevét-1 well, the amount of reservoir sand is less than expected. Further studies will be required to determine the significance of the Tevét-2 result. At midnight on 26 September 2005, preparations were underway to drill to the next casing point. The well will then target a deeper exploration prospect. The planned total depth of the well is approximately 3,965 metres.
Chinguetti Development Wells The 'West Navigator’ drillship continues to perform completion work on Chinguetti Development wells. Woodside does not plan to issue regular announcements regarding operations on Chinguetti development wells but will do so if necessary to comply with its continuous disclosure obligations under the ASX Listing Rules.
General All reported drilling depths are referenced to the rig rotary table and all times are Universal Time (UTC) (Mauritanian time). The locations of planned exploration wells and the Chinguetti Oil Field are shown on the attached map."

| TEVÉT-2 PRELIMINARY RESULTS, OFFSHORE MAURITANIA: (26-09-2005) |
The well has drilled through the Miocene channel sand system which constitutes the shallower of the well's two objectives. The well will now be deepened to test a separate Cretaceous target with a planned total depth of approximately 3,965 metres. Preliminary information from drilling and log results to date suggest that the well has encountered hydrocarbon-bearing sands in a sequence that bears comparison to the equivalent channel section drilled by the 2004 discovery well (Tevét-1) approximately 3km to the north. <view map>. Further comment regarding the significance of Tevét-2 cannot be made until additional information being acquired has been analysed and completed.

| CHINGUETTI SCHEDULE AND COST: (20-09-2005) |
"The Woodside-operated offshore Chinguetti oil development in Mauritania remains on schedule for first oil in February 2006. The project is 88% complete. The Chinguetti joint venture has completed an update of estimated project costs. Known project costs to complete the installation and start-up total US$705 million. An additional US$45 million has been set aside to cover unplanned contingencies that may occur during the offshore, deep-water installation program. The current project cost estimate is primarily a result of increased drilling scope due to complex geology, resulting in extra time to drill sidetracks, as well as additional costs to prepare the subsea flowlines for installation. The Chinguetti joint venture is operated under a production sharing contract subject to project cost recovery. Chinguetti joint venture interests are: Woodside 47.38448%; Hardman Resources 19.00800%, BG Group 10.23440%, Premier 8.12328%, Roc Oil 3.24984% and Groupe Projet Chinguetti 12%."

"Woodside Mauritania Pty. Ltd., a wholly-owned subsidiary of Woodside Petroleum Ltd., reports the following activity offshore Mauritania since the last report issued on 13 September 2005.
The Espadon-1A well was plugged and abandoned on 15 September 2005 following analysis of wireline logs which indicated no significant hydrocarbons were encountered in the well. The Tevét-2 well was spudded on 16 September by the ‘Stena Tay’ drill rig and has been drilled to a depth of 1,510 metres where casing has been set. The Tevét-2 well is located 2.5km to the south of the discovery well Tevét-1, in a water depth of 466 metres. The Tevét-2 well is a combined exploration and appraisal well to both appraise the Tevét discovery and target a deeper exploration prospect beneath the Tevét Miocene reservoir. The planned total depth of the well is approximately 3,965 metres. At midnight on 19 September 2005, preparations were underway to drill ahead to the shallower of two objectives. Chinguetti Development Wells The 'West Navigator’ drillship continues to perform completion work on Chinguetti Development wells. Woodside does not plan to issue regular announcements regarding operations on Chinguetti development wells but will do so if necessary to comply with its continuous disclosure obligations under the ASX Listing Rules.
