For years, Darwin citizens were fascinated about poisonous chemical substances emitted via town’s two gasoline export amenities.
If truth be told, some locals are so fearful about those airborne chemical substances – in particular benzene – they lately shaped a neighborhood crew and introduced a fundraiser to shop for a regulation-grade cell software for steady tracking.
Most effective days later, the Northern Territory Surroundings Coverage Authority (NTEPA) licensed a allow extension permitting global gasoline massive Santos to emit – or “hot vent” – poisonous gases and unstable natural compounds (VOCs), reminiscent of benzene, for an additional 26 days each and every 12 months. Santos already has permission to emit for 36 days each and every 12 months.
The proof displays 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
A number of the many hazardous gases launched into the ambience right through gasoline and Liquified Herbal Fuel (LNG) manufacturing, benzene is among the maximum relating to.
Many fresh research hyperlink benzene publicity to vital well being dangers, each on my own and with different “BTEX” chemical substances (toluene, ethylbenzene and xylene).
Those dangers come with cancers, formative years bronchial asthma, center and respiration illnesses, hospitalisations and deaths, low start 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’s no secure degree of publicity to benzene. Each section in step with billion other folks inhale issues.
In 2004, the Australian executive dedicated to study proof and set a proper same old for benzene publicity via 2012, however none has been set. The extent of benzene that triggers an investigation in Australia is 2 to 3 instances upper than benzene requirements throughout Europe, India, Japan and New Zealand.

Permission to emit
Darwin has two LNG export amenities, operated via Jap massive Inpex and world power company Santos. They’re respectively situated about 10 kilometres from Darwin’s central industry district.
Citizens involved in regards to the ranges of benzene and different poisonous chemical substances being emitted via those two vegetation lately shaped a bunch known as Group Wholesome Air Northern Territory (CHANT).
Introduced on June 14, CHANT has raised greater than $100,000 to shop for a regulation-grade cell BTEX tracking software. The neighborhood is lately gaining recommendation from professionals to habits their very own air tracking mission.
The day after this crew was once introduced, NTEPA introduced its personal plans to determine an air-quality trying out community. The authority stated this might measure and file on poisonous air ingredients, together with BTEX chemical substances.
But most effective two days later, the authority licensed the extension – permitting Santos to “hot vent” poisonous waste gases from its new arguable Barossa gasoline provide for an extra 26 days. Scorching venting is when waste gasoline is launched immediately into the ambience, bypassing anti-pollution gadgets.
Considerations over priorities
Some Darwin citizens see this extension for example of the concern given to the gasoline trade over the neighborhood considerations.
This view has benefit. As an example, in 2025 an ABC Darwin investigation printed Santos didn’t file a major leak in its LNG garage tank for twenty years. Regardless of huge volumes of methane escaping, Santos isn’t required to fix the crack.
In 2024, Darwin citizens changed into conscious Inpex LNG had emitted VOCs, reminiscent of benzene, as much as 22 instances upper than it in the beginning estimated it will.
In 2025, Inpex admitted to underestimating benzene emissions via 138 instances in obligatory reporting of general VOCs, most probably since 2018. It additionally admitted to sizzling venting for prolonged sessions of time when the corporate’s anti-pollution gadgets weren’t running.
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 information and per 30 days measurements of BTEX chemical substances in ambient air samples at 4 neighborhood places, in addition to the gasoline plant boundary. This file was once no longer made public.
A 2d consultancy discovered basic deficiencies in INPEX’s emissions calculation methodologies, that means sizzling venting emissions had been constantly underestimated via 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 spoke back?
This raises some severe questions. The standard of the file effects relies totally at the high quality of the enter information. Steady air high quality measurements, no longer simply per 30 days sampling, are wanted. If benzene is systemically under-reported, then publicity estimates and doable well being affects is also considerably underestimated.
Previous exposures will have to be investigated urgently. As a result of air high quality measurements ceased at their top in October 2021, well being research shall be had to assess any opposed well being results in years to come, in particular in youngsters.
More potent motion wanted
Given the proof, we urge the government’s Nationwide Surroundings Coverage Council to rigorously evaluate the various fresh inhabitants research that disclose severe dangers of publicity ranges beneath the ones lately regarded as ‘safe’.
We watch for actually protecting brief and long run requirements for benzene and general BTEX publicity that should be acted upon when exceeded. The NT EPA and executive should take complete accountability to make sure emissions of those pollution are minimised for other folks and their setting.
Getting this at the moment is important for Darwin, and impulsively rising gasoline tendencies the world over. Transparent limits to poisonous emissions, cautious unbiased tracking and company regulatory motion is very important to offer protection to other folks.
