assurance that its goals will be met. Actual results may vary significantly from
those anticipated due to many factors, including oil and gas prices, operating
hazards, drilling risks, environmental risks and uncertainties in interpreting

risks discussed in the Company's SEC filings.

                     PETSEC CONTINUES EXPANDED 2005 PROGRAM
                    WITH SPUDDING OF NEW GULF OF MEXICO WELL

Petsec Energy Ltd (ASX, PSA; ADR's, PSJEY.PK)

SYDNEY, Australia:- Petsec Energy Limited has continued its expanded 2005
exploration and development program with the spudding on Saturday (23
April) of the Main Pass 19 #1 well in the Gulf of Mexico, USA.

The new well - located 128 kilometres (80 miles) south east of New Orleans
- - is the first in a program of two to three wells to be drilled from the
same location to test mapped potential of approximately 12 billion cubic
feet to 15 billion cubic feet equivalent of natural gas (net to Petsec).

An existing platform and jacket have been acquired and a sales pipeline is
in close proximity to the drilling location, allowing commercial
discoveries to be brought into production within a few months.

Drilling of the Main Pass 19 #1 well follows the announcement last month by
Petsec that its exploration and development budget for 2005 had been set at
A$32 million (US$25 million).

The budget - which includes a more active exploration component - allows
for the drilling and development of 7 wells in the USA and China, a 94
square mile 3D seismic survey onshore USA, and a feasibility study and Oil
Development Plan for the 12.8 West oil field in China.

Details of the newly-spudded Main Pass 19 #1 well are as follow:-
