                         ROC OIL COMPANY LIMITED ('ROC')
                             STOCK EXCHANGE RELEASE

                            ACTIVITY UPDATE - ANGOLA

KEY POINT

•   ROC is progressing its Angolan activities on several fronts including
    the establishment of a senior executive team in Luanda and preparations for
    a substantial onshore seismic survey.

1.  Senior Executive Appointments

ROC is pleased to announce the following senior executive appointments:

•   Mr Antonio Vieira has been appointed President of Roc Oil (Cabinda)
    Company. This is the wholly owned subsidiary through which ROC currently
    owns the majority of its interest in the Cabinda South Block, onshore
    Angola. Mr Vieira, an engineer by training with qualifications from Luanda,
    Lisbon and Texas A & M University, has been with ROC for five years, mainly
    as the Company's Representative in Africa. Sydney-based Mr Vieira speaks
    several languages including Portuguese and will spend a significant amount
    of time in Luanda and Cabinda.

•   Dr Ken Seymour has been appointed General Manager-Angola. With more than 25 
    years experience in the international oil industry, Dr Seymour started his 
    career with BP and subsequently spent 19 years with the former Ranger Oil 
    Limited, now CNR International, primarily in Angola. Since he first started
    working in Angola in 1995, Dr Seymour has held a variety of senior executive
    positions in that country including Drilling/Country Manager, Operations 
    Manager and General Manager. Dr Seymour is fluent in Portuguese and will be
    based in Luanda.

2.  Seismic Survey

As operator of the Cabinda South Joint Venture, ROC is currently in final
discussions with regard to a contract to acquire 165sqkm of 3-D and 500km of 2-D
seismic, onshore Cabinda. The imminent seismic survey will be the first phase of
a two phase seismic programme the second part of which will be undertaken in
2006. This forward exploration plan is consistent with the Company's previously
announced activity schedule which envisages first drilling in late 2006 or 2007.

The seismic survey, which will be the first on-the-ground oil exploration
activity to occur onshore Angola for more than 30 years, will be a landmark
event for ROC. The survey is designed to detail numerous prospects and leads
which have been identified from the pre-1972 seismic which shows a multiplicity
of structuring (eg Attachments 1 - 4*).

All existing wells in the Cabinda South Block were drilled prior to 1972 and
were primarily located on a combination of poor quality, single fold seismic
data, surface geology and gravity anomalies. Despite this sparse exploration
framework, a number of the wells drilled in the Cabinda South Block encountered
significant oil and gas shows and, in some cases, flowed and/or recovered oil
and gas to surface.

Further details of the geology and perceived prospectivity of the Cabinda South
Block are contained in previous public announcements by ROC and can be found on
the Company's website.

3.  Portfolio Management

ROC continues to progress its previously announced strategy of farming out a
minority portion of its equity in the Cabinda South Block.

4.  Marburg Virus

Considered advice from various sources within Angola, suggests that the recent
outbreak of the Marburg Virus, which has received widespread media coverage in
various parts of the world, is not expected to impact on the Company's
operations in Cabinda. However, for all the obvious Health, Safety and
Environmental reasons ROC will continue to monitor the situation very closely.
