                             STOCK EXCHANGE RELEASE

                          EXPLORATION DRILLING UPDATE
                    PERTH BASIN, OFFSHORE WESTERN AUSTRALIA

Further to its Stock Exchange release on 31 July 2006, Roc Oil (WA) Pty Limited
advises that the ENSCO 67 jack-up drilling rig relocated to the Frankland-1
exploration well location in WA-286-P on 11 August 2006.

Due to adverse weather conditions it was not possible to commence drilling the
Frankland-1 exploration well prior to the expiry of the drilling rig contract.
As a result the ENSCO 67 was released on 11 August 2006 and the offshore Perth
Basin development and exploration drilling programme concluded.
