Federal Energy Minister Chris Bowen has signaled a significant policy shift, asserting that future gas projects in Australia must prioritize domestic supply, moving away from an exclusive export model. This declaration comes as the government launches a comprehensive review of the nation's gas market regulations, aiming to ensure sufficient and affordable energy for Australian consumers and industries. The move underscores growing concerns over energy security and the evolving dynamics of Australia's energy transition.The review, which consolidates three existing regulatory frameworks, seeks to streamline the complex rules governing the domestic gas market. Minister Bowen emphasized that while the existing gas code of conduct is effective, the government is exploring "sensible, holistic, carefully designed, well-calibrated opportunities" to guarantee Australian users access to Australian gas. This approach is a direct response to a consultation paper highlighting that new east coast gas projects are not emerging quickly enough to offset the decline of existing fields, potentially leading to supply shortfalls.Major projects, including Santos's $3.6 billion Narrabri Gas Project and Woodside's proposed Browse development off Western Australia, alongside pilot initiatives in the Northern Territory's Beetaloo Basin, are progressing towards approval. The Minister's stance implies that these and other future developments will face increased scrutiny regarding their commitment to domestic supply. "New supply wholly for export will not help Australia's domestic gas needs," Bowen stated, reinforcing the government's expectation for local market contributions.The policy adjustment is particularly pertinent for the east coast, where gas plays a crucial role in balancing the grid, especially as renewable energy penetration increases. While not a direct gas reservation scheme, which the Labor government previously opposed, the new framework aims to achieve similar outcomes by influencing investment decisions towards domestic supply. This could impact the economic viability and development timelines of large-scale gas projects, potentially redirecting capital or altering project structures.Industry stakeholders, including Australian Energy Producers CEO Samantha McCulloch, have largely welcomed the review, acknowledging the need for regulatory simplification to "future-proof the east coast gas market." However, McCulloch stressed the importance of "restoring market signals" to encourage investment in Australia's abundant gas resources, which she believes will remain critical to the energy mix for decades. Conversely, the Coalition, through Shadow Resources Minister Susan McDonald, criticized the government's existing market interventions, arguing they have deterred investment and jeopardized Australia's international trading reputation.This regulatory re-evaluation highlights the delicate balance Australia seeks to strike between its role as a major energy exporter and its domestic energy security requirements. For the renewable energy sector, a stable and predictable gas market, whether as a firming fuel or a competitor for industrial demand, is crucial. Policy certainty around gas supply can indirectly influence investment in renewable energy infrastructure by affecting grid stability, industrial energy costs, and the overall confidence in Australia's energy transition pathway. The outcome of this review will significantly shape the investment landscape for both traditional and clean energy projects in the coming years.
