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

'Woodside Petroleum Ltd. Reports the following activity by its wholly-owned
subsidiary Woodside Mauritania Pty. Ltd. in offshore Mauritania since the last
report issued on 28 October 2005.

PSC Area B: Tevet- 2 and Tevet-2 ST1 Combined Appraisal and Exploration Well

The 'Stena Tay' drill rig completed wireline logging operations of the
Cretaceous exploration objective of the Tevet-2 sidetrack ('ST1'). This included
recovery of oil and rock samples to surface, which established that the
exploration well intersected a gross oil column, now expected to be
approximately 6 metres.

At midnight on 31 October 2005, the well was being plugged and abandoned prior
to the rig moving to the Labeidna-1 exploration well location. Labeidna-1, which
is located 15 kilometres to the south-west of Chinguetti field, will target
Miocene sands.
                                    General

All reported drilling depths are referenced to the rig rotary table and all
times are Mauritanian time, which is the same as Universal Time.

The locations of planned exploration wells, including the addition of Zoule
exploration well in PSC-C Block 6, and the Chinguetti Oil Field are shown on the
attached map*.'
