Naturally occurring asbestos

It's important everyone knows what to do if they come into contact with naturally occurring asbestos (NOA).

This page provides information on NOA, and supporting documents on what you can do to avoid contact with NOA.

Asbestos is naturally occurring and can typically be found in rock (including serpentinite), sediment, or soil.

Naturally occurring asbestos can be:

  • white (chrysotile)
  • brown (actinolite, amosite)
  • blue (anthophyllite, crocidolite)
  • tremolite

Depending on the probability of naturally occurring asbestos being present, NSW has been mapped into low, medium, or high potential regions. Please refer to the mapping report when reviewing the mapping,

Less than 1 per cent of NSW is considered high potential.

The NSW Government's Heads of Asbestos Coordination Authorities has released information on these areas. This information is indicative only. If in doubt you may like to do onsite testing whether naturally occurring asbestos is present.
