Item 5.  Other Events and Regulation FD Disclosure
         -----------------------------------------

     Magellan Petroleum Corporation, a Delaware corporation (NASDAQ: MPET) (the
"Company") is filing this current report on Form 8-K in order to report the
following event involving the Company.

     Acquisition of Shares of Magellan Petroleum Australia Limited
     -------------------------------------------------------------

     On September 2, 2003, the Company completed its previously announced
acquisition of 1,200,000 shares of its majority-owned subsidiary, Magellan
Petroleum Australia Limited ("MPAL") from Sagasco Amadeus Pty Limited
("Sagasco"), a subsidiary of Origin Energy Limited, a diversified energy company
based in Sydney, Australia. The acquisition of MPAL shares by the Company was
made pursuant to a share sale agreement entered into by the Company and Sagasco,
dated as of July 10, 2003 (the "Share Sale Agreement"). The MPAL share
acquisition followed the receipt of governmental approval in Australia and has
increased the Company's holdings in MPAL from 52.4% to approximately 55%.

     In consideration for its receipt of the MPAL shares, the Company issued to
Sagasco 1,300,000 shares of its common stock, par value $.01 per share (the
"common stock") in a private placement transaction conducted outside the United
States pursuant to the exemption from registration provided by Regulation S
under the Securities Act of 1933, as amended (the "Securities Act"). The
1,300,000 shares of common stock have not been registered under the Securities
Act and may not be offered or sold in the United States absent registration or
an applicable exemption from the registration requirements of the Securities
Act.

     At the closing, the Company also entered into a registration rights
agreement with Sagasco, dated as of September 2, 2003 (the "Registration Rights
Agreement"), pursuant to which the Company has agreed to register, upon receipt
of a written demand by Sagasco, the 1,300,000 shares of common stock for public
resale by Sagasco under the Securities Act. Sagasco has notified the Company of
the exercise of its rights under the Registration Rights Agreement to cause the
Company to prepare and file a registration statement under the Securities Act
covering the public resale by Sagasco of the 1,300,000 shares. The Company
intends to promptly prepare and file a registration statement for this purpose.

     The Company intends to file copies of the Share Sale Agreement and the
Registration Rights Agreement as exhibits to its annual report on Form 10-K to
be filed with the Securities and Exchange Commission on or before September 28,
2003.
