ASX Release

Hovea 7 Progress Report, Onshore Perth Basin, Western Australia

Origin Energy Resources Limited* advises that subsequent to the completion of the Hovea 7 well and the removal of the Century drilling rig to the Eremia 1 location, the well has been perforated and an initial flow test performed. The initial flow results, together with the results of through casing logs (CNL) suggest that the southern end of the field in the Hovea 7 area contains a gas cap overlying the oil zone. This is unlikely to have a material effect on the size of the oil reserves. The current program at the well is acquiring pressure data prior to a possible production test.

The Century drilling rig has now been moved to the Eremia 1 location and the well is expected to spud within the next 24 hours. The Eremia 1 exploration well is a vertical exploration well targeting multiple Permian targets in a fault dependent anticlinal closure. The well is located approximately 2.5 kilometres west of the Hovea Production Facility.

Participants in Hovea 7 and Eremia 1 are as follows:

Origin Energy Developments Pty Limited*		50.00%
Arc Energy NL (Operator)		50.00%

*a wholly owned subsidiary of Origin Energy Limited

Media Release

10 March 2003

Origin Energy responds to NECA report

The National Electricity Code Administrator Ltd (NECA) has released a report today into the events in the national electricity market on Saturday 25 January 2003.

The Report indicates that, for a limited time during this period, Origin Energy Electricity Limited breached the requirement for generators to be at all times able to comply with their latest generation dispatch offers under the National Electricity Code (the Code) in relation to its operations at the Ladbroke Grove Power Station in the South East. Origin agrees that it has breached the Code.

On Saturday 25 January 2003, Unit 1 of Origin’s Ladbroke Grove Power Station suffered a minor technical fault and tripped out. During the 90 minute period the unit was off-line, Origin’s duty trader bid the unit into the market thereby indicating that the unit was still available. This action was in breach of Origin’s own operating procedures and resulted in a breach of the Code. The Company procedure requires that following such a unit trip, that unit be withdrawn from the market until the fault is rectified.

As NEMMCO did not call upon the unit while it was offline, the bid had no impact on the market price.

Tony Wood, General Manager Public and Government Affairs said, “Origin regrets this breach of the Code and has taken steps to ensure it will not re-occur. This was a genuine error in administering the procedures of the company and the Code, and occurred on a day when there were other significant issues in the South Australian energy markets.

Origin is committed to ensuring compliance in its business activities and is taking this issue very seriously.”

Origin Energy US Private Placement Debt Issue

Origin Energy today completed the issue of USD250 million of senior unsecured notes into the US private placement market. The notes were issued in three tranches maturing 2010, 2015 and 2018. The proceeds from the notes have been fully converted to Australian dollars and all future US dollar and US interest rate exposure arising from the notes has been fully hedged.

Frank Calabria, Chief Financial Officer of Origin Energy said “The issue diversifies Origin’s sources of funding and significantly lengthens the debt maturity profile of the company. The transaction provides long term certainty of debt financing without any increase in financing margins compared to Origin’s existing domestic medium term financing facilities. Proceeds from the issue have been used to repay existing bank debt. This issue combined with the company’s strong cash flow means that Origin continues to be well placed to take advantage of further growth opportunities.”

Joint Lead Arrangers to the Issue were Banc of America Securities and Westpac Institutional Bank.

Origin Energy Limited is currently rated by Fitch Ratings as A-/Stable and by Standard and Poor’s as BBB+/Stable.

Dear Shareholder

DIVIDEND REINVESTMENT PLAN (DRP) - CHANGE OF DISCOUNT

Under the DRP shares allotted have been issued at a discount of 5% to the volume weighted average market price (VWAP) in the five days prior to books close. This discount has applied in respect of the last two dividends.

The Board has announced that the level of dividend will be increased to a target rate of 40% of net earnings per share, irrespective of the level of franking credits available. Consequently, the Board has decided to reduce the level of discount under the DRP to 2.5% which will apply to future dividends paid. This will be calculated on the VWAP for the five days of trading up to and including the books closing date.

Should you wish to participate in the DRP or change your participation for future dividends you should complete and return the DRP election form enclosed. If you do not return this form your existing dividend election will be retained. The completed form should be signed by you and returned in the reply paid envelope before the books closing date of the next dividend.

If you have any questions about this dividend or the DRP please call the Share Registry on 1300 664 446. Copies of the DRP terms and conditions can be obtained by calling this number or can be accessed on our website www.originenergy.com.au.

Yours sincerely

/s/ W M Hundy

ASX Release

Eremia 1 Progress Report, Onshore Perth Basin, Western Australia

Origin Energy Resources Limited* advises that the exploration well Eremia 1 operated by ARC Energy NL and located in the onshore Perth Basin Production Licence L1, was at 0600 hours WST preparing to run 9 5/8 inch casing at a depth of 2161 metres.

The top of the Dongara Sandstone was encountered at 2095 metres measured depth, 23 metres high to prognosis. Good oil shows were noted down to 2110 metres measured depth. Interpretation of wireline logs and pressure measurements has confirmed that the well has intersected an oil column of at least 15 metres and possibly up to 18 metres in excellent quality Dongara Sandstone reservoir.

Once casing has been run the Eremia 1 well will be deepened in 8½ inch hole to a proposed total depth of 2700 metres to intersect deeper reservoir targets, known to be gas bearing in the nearby Hovea Field.

Participants in L1 and L2 (excluding the Dongara, Mondarra and Yardarino fields), and Eremia 1 are:

Origin Energy Developments Pty Limited*		50.00%
Arc Energy NL (Operator)		50.00%

*a wholly owned subsidiary of Origin Energy Limited

Origin Energy Resources Limited* advises that the exploration well Eremia 1 operated by ARC Energy NL and located in the onshore Perth Basin Production Licence L1, was at 0600 hours WST completing abandonment activities at a total depth of 2550m.

Eremia 1 intersected an oil column of at least 15 metres and possibly up to 18 metres in excellent quality Dongara Sandstone reservoir. This zone was subsequently cased for future production and the well drilled ahead in 8 ½ inch hole. The Irwin River Coal Measures sequence and High Cliff Sandstone, gas bearing in the nearby Hovea Field, are interpreted from wireline logs to be water bearing at the Eremia location.

Cement plugs will now be run to isolate these zones prior to the well being completed for production from the Dongara Sandstone oil reservoir.
