The text discusses the uncertainty surrounding Australia as a stable LNG supplier and Japan's efforts to diversify its import portfolio. The Japanese government wants to ensure a stable energy supply and maintain investment certainty during this transition period. However, Japan is facing challenges in its push for a major LNG export development in Australia, as the Albanese government resists giving it special treatment. Despite this, there is still strong foreign investment in Australia's oil and gas sector. Japan has also criticized Australia's policy measures for achieving net zero emissions and called for a portfolio approach to investment in new energy projects to reduce risk. According to Australian Minister for Resources Madeleine King, more investment is needed in the gas industry to secure future supply. However, Japan and Australia are still working together, as evidenced by a recent deal between LNG Japan and Australia's Scarborough project. Japan is worried that proposed revisions to Australia's gas security guidelines could have negative effects on LNG trade and investments.
