Queensland's coal seam gas industry has grown rapidly over the last twenty years and as at the end of 2024, there were over 12,000 coal seam gas (CSG) wells across inland Queensland.
The Maranoa and Western Downs regions of the Surat Basin currently host the majority (approx 84%) of Queensland’s CSG activities with the remainder in the southern Bowen Basin (central Qld).
Shining a spotlight on dangerous gas infrastructure
Lock the Gate has launched a new program with high-tech methane detection drone technology to expose dangerous methane leaks from gas infrastructure.
These methane leaks pose an explosive risk to local communities, and has a disastrous impact on global heating, as methane is a climate-heating super gas. It is a whopping 84 times more potent than carbon dioxide in the short term and is contributing to the terrible climate impacts we are seeing in our communities today.

Coal Seam Gas in Queensland
An increasingly large body of scientific and anecdotal evidence is revealing the devastating impact the CSG industry is having both above and below the ground in some of Queensland’s best farming regions.
In September 2022, a report published in the journal Proceedings of the Royal Society of Queensland, found the more than 22,000 wells planned for Southern QLD could cause irreversible damage.
A big part of the report’s concerns focused around how CSG extraction was causing farmland to subside –an issue that has had a financial burden on farmers near Dalby due to the impact on cropping production. The government only publicly admitted it was a problem in April 2022.
Scandals are rocking Queensland’s coal seam gas industry at an increasingly frequent rate as projects spread out over the state’s best farmland.
The biggest penalty handed to a company for wrongdoing so far was in March 2022 when Shell and PetroChina owned Arrow Energy, which is developing its 8,600 square kilometre Surat Gas Project, was fined $1 million for illegally drilling deviated wells beneath farmers’ land without permission.
Origin Energy has also been in the news after it was fined a mere $60,000 in the Brisbane Magistrates Court for releasing nearly one billion litres of contaminated coal seam gas wastewater to spill onto farmland and into waterways near Wandoan.
In early 2023, a new incidence of gas bubbling from the Condamine River was reported, raising the alarm that methane seeps into the waterway are more widespread than previously revealed, amid the continued ramp-up of coal-seam gas drilling in the Darling Downs.
Despite allowing the coal seam gas industry to spread across vast areas of the state, the State Government still has no formal policy for how gas companies should dispose of the six million tonnes of waste the industry is expected to produce. This waste is heavily laden with salt and heavy metals, and experts say it would need to be monitored “in perpetuity” to prevent contamination.

The release of the Qld Government's long-awaited CSG Brine Management Action Plan in early 2023 has sparked fears for the health of the Murray-Darling River System. The plan concludes that the most likely option for the 5-6 million tonnes of toxic “brine” will be to store it in landfill within “lining” - a solution that independent scientists say is fraught with risks, including that the lining would fail, especially during flood events, and that the stored waste could then leach into the environment over time.

There are over 12,000 coal seam gas wells drilled in Queensland - with many of them on some of Australia’s best agricultural land. The government must act urgently to protect farmland and water from the impacts of coal seam gas, such as water contamination, subsidence of farmland, dumped waste products and methane pollution.
This requires strict no-go zones for gas mining on Queensland’s most productive farmland, strong protections for underground water and closing the planning loopholes that allow gas companies to continue to expand on prime agricultural land.
Prior to the Queensland election, the LNP government committed to better protections for the Condamine Alluvium- the water source that sits beneath some of Queensland's best agricultural land.
To Jarrod Bleijie, Deputy Premier, Minister for State Development, Infrastructure and Planning.
The Darling Downs is home to some of the most productive farmland in Queensland. But for years, Darling Downs farmers have been fighting to protect this prime agricultural land from destructive gas drilling by Arrow Energy.
The undersigned calls on you to support farmers attempting to protect their land and water, and our food and fibre security, from the irreversible impacts of Coal Seam Gas mining.
In March 2026, the LNP introduced laws into Queensland Parliament which are a cruel betrayal of Downs farmers. Rather than strengthen protections for the Condamine Alluvium as promised, the laws are instead a golden handshake for Arrow Energy, the multinational gas company owned by Shell and PetroChina threatening the Downs with gas drilling.
The LNP have made it easier for gas companies to decimate Queensland’s best farmland on the Condamine Floodplain with century-long consequences.
This is an urgent issue for the people of Queensland and requires immediate action from the government to prevent further damage and allow Queensland farms to continue to feed and clothe our State and the world.
