For years, Darwin citizens had been involved in poisonous chemical substances emitted by means of town’s two fuel export amenities.
Actually, some locals are so frightened about those airborne chemical substances – specifically benzene – they not too long ago shaped a group team and introduced a fundraiser to shop for a regulation-grade cellular instrument for steady tracking.
Handiest days later, the Northern Territory Atmosphere Coverage Authority (NTEPA) authorized a allow extension permitting global fuel large Santos to emit – or “hot vent” – poisonous gases and unstable natural compounds (VOCs), reminiscent of benzene, for an additional 26 days each and every yr. Santos already has permission to emit for 36 days each and every yr.
The proof presentations benzene and different gas-related chemical substances pose vital well being dangers. So why is the NT prepared to green-light this extra pollutants with out extra rigorous tracking?
Why benzene publicity is an issue
Some of the many hazardous gases launched into the ambience throughout fuel and Liquified Herbal Fuel (LNG) manufacturing, benzene is likely one of the maximum regarding.
Many fresh research hyperlink benzene publicity to vital well being dangers, each by myself and with different “BTEX” chemical substances (toluene, ethylbenzene and xylene).
Those dangers come with cancers, adolescence bronchial asthma, middle and respiration illnesses, hospitalisations and deaths, low beginning weight and most cancers dangers to the creating fetus, even at low ranges of publicity in out of doors environments.
The analysis is obvious: there is not any protected stage of publicity to benzene. Each section according to billion folks inhale issues.
In 2004, the Australian govt dedicated to study proof and set a proper usual for benzene publicity by means of 2012, however none has been set. The extent of benzene that triggers an investigation in Australia is 2 to a few occasions upper than benzene requirements throughout Europe, India, Japan and New Zealand.

Permission to emit
Darwin has two LNG export amenities, operated by means of Jap large Inpex and world power company Santos. They’re respectively situated about 10 kilometres from Darwin’s central trade district.
Citizens involved in regards to the ranges of benzene and different poisonous chemical substances being emitted by means of those two crops not too long ago shaped a gaggle known as Neighborhood Wholesome Air Northern Territory (CHANT).
Introduced on June 14, CHANT has raised greater than $100,000 to shop for a regulation-grade cellular BTEX tracking instrument. The group is lately gaining recommendation from professionals to habits their very own air tracking undertaking.
The day after this team used to be introduced, NTEPA introduced its personal plans to determine an air-quality trying out community. The authority stated this may measure and file on poisonous air ingredients, together with BTEX chemical substances.
But handiest two days later, the authority authorized the extension – permitting Santos to “hot vent” poisonous waste gases from its new arguable Barossa fuel provide for an extra 26 days. Scorching venting is when waste fuel is launched immediately into the ambience, bypassing anti-pollution gadgets.
Issues over priorities
Some Darwin citizens see this extension for instance of the concern given to the fuel business over the group issues.
This view has advantage. For instance, in 2025 an ABC Darwin investigation printed Santos didn’t file a major leak in its LNG garage tank for two decades. Regardless of huge volumes of methane escaping, Santos isn’t required to fix the crack.
In 2024, Darwin citizens become conscious Inpex LNG had emitted VOCs, reminiscent of benzene, as much as 22 occasions upper than it initially estimated it will.
In 2025, Inpex admitted to underestimating benzene emissions by means of 138 occasions in obligatory reporting of overall VOCs, most probably since 2018. It additionally admitted to sizzling venting for prolonged classes of time when the corporate’s anti-pollution gadgets weren’t working.
In 2025, Inpex commissioned a consultancy to habits desktop modelling of estimated ranges of benzene and toluene throughout within reach spaces in larger Darwin. The modelling used Inpex’s personal emissions knowledge and per thirty days measurements of BTEX chemical substances in ambient air samples at 4 group places, in addition to the fuel plant boundary. This file used to be no longer made public.
A 2nd consultancy discovered elementary deficiencies in INPEX’s emissions calculation methodologies, that means sizzling venting emissions had been constantly underestimated by means of a number of orders of magnitude.
It additionally discovered a couple of further flaws, reminiscent of deficient documentation, inconsistencies and incomplete protection of all emission resources.
How has the federal government answered?
This raises some critical questions. The standard of the file effects is dependent fully at the high quality of the enter knowledge. Steady air high quality measurements, no longer simply per thirty days sampling, are wanted. If benzene is systemically under-reported, then publicity estimates and possible well being affects could also be considerably underestimated.
Previous exposures will have to be investigated urgently. As a result of air high quality measurements ceased at their height in October 2021, well being research will likely be had to assess any opposed well being results in years to come, specifically in kids.
More potent motion wanted
Given the proof, we urge the government’s Nationwide Atmosphere Coverage Council to rigorously evaluation the various fresh inhabitants research that expose critical dangers of publicity ranges under the ones lately regarded as ‘safe’.
We anticipate really protecting quick and longer term requirements for benzene and overall BTEX publicity that should be acted upon when exceeded. The NT EPA and govt should take complete duty to make sure emissions of those pollution are minimised for folks and their atmosphere.
Getting this at the moment is important for Darwin, and abruptly rising fuel trends internationally. Transparent limits to poisonous emissions, cautious unbiased tracking and company regulatory motion is very important to offer protection to folks.
