We’ve safely developed coal seam gas (CSG) since 2000. Our Moranbah Gas Project in central Queensland, Australia’s largest CSG gas field, has supplied gas to the domestic market since 2004. In 2006, we became the first to supply gas domestically from the Surat Basin in south-east Queensland. Today Arrow has 5 gas fields in production in the Bowen and Surat basins, which deliver about 20% of Queensland’s gas supply. We own or have interests in 3 gas-fired power stations, capable of powering 800,000 homes. In a little more than a decade, Arrow has become an internationally-backed, experienced industry leader, well-placed to deliver a multi-billion dollar CSG to LNG project for Australia. Backed by global oil and gas giants, Shell and PetroChina, Arrow will safely and sustainably connect world markets with Queensland’s natural gas. Importantly we’re committed to giving local businesses full, fair and reasonable opportunity to join the journey.
