Communities across central west New South Wales are demanding urgent assurances from authorities over potential health risks as vehicles kick up dust along unsealed council roads cutting through naturally occurring asbestos deposits.

A geological belt bearing naturally occurring asbestos runs through sections of regional NSW, leaving rural residents fearful that daily traffic is disturbing dangerous mineral fibres, ABC News NSW reported. Naturally occurring asbestos is found within specific rock formations across the state, notably in pockets of ultramafic rock throughout the Central West. While relatively benign when undisturbed beneath undisturbed topsoil and vegetation, the mineral presents severe respiratory hazards once ground into fine particles and dispersed into the air.

A geological hazard beneath the gravel

Many rural routes in the region were constructed decades ago using local shale, decomposed granite, or river gravel sourced from nearby quarries without contemporary mineral testing. In several areas, unpaved shire roads traverse directly over exposed bedrock containing fibrous minerals such as chrysotile and tremolite.

Whenever council graders carry out routine maintenance, or heavy agricultural machinery and school buses traverse these corridors, thick plumes of dust linger over paddocks and properties. ABC News NSW reported that locals want authoritative information regarding the mineral composition of their road surfaces and whether daily commuting presents an elevated risk of airborne fibre inhalation.

Dust, drought and daily exposure concerns

In the dry, windy conditions typical of the inland plains, dust drift poses an ongoing management challenge. Landholders whose homesteads sit within close proximity to unsealed roads have voiced persistent concern about fine sediment settling on roofs, infiltrating rainwater harvesting tanks, and coating verges grazed by livestock.

Residents have questioned whether existing land management guidelines adequately account for prolonged, low-level environmental exposure. While occupational guidelines for asbestos removalists are well established, community members report feeling left in the dark regarding the baseline safety of living along an unsealed road known to contain fibrous strata.

Councils balance infrastructure costs against health risks

Local shires are caught between demanding road maintenance obligations and constrained regional budgets. Sealing hundreds of kilometres of unpaved road network requires tens of millions of dollars that rural ratepayer bases cannot generate independently.

Under state environmental and planning frameworks, councils are required to implement Naturally Occurring Asbestos Management Plans. These strategies often involve capping compromised corridors with imported, verified clean road base, applying chemical dust-suppression binders, or avoiding aggressive grading during dry weather. However, rural communities point out that heavy rain events frequently wash away surface caps, exposing the underlying geological formations once again.

Calls for clearer monitoring and state intervention

With anxiety growing across the Central West, community advocates are calling for coordinated intervention from the state government, including active air-quality monitoring and dedicated infrastructure funding.

While SafeWork NSW and the NSW Environment Protection Authority provide public mapping tools and general advisory material on naturally occurring minerals, residents maintain that regional shires require direct financial support from the state to permanently seal affected routes. Until comprehensive testing and lasting infrastructure upgrades are delivered, families living alongside these unsealed arteries remain deeply unsettled about the air they breathe every day.
