Sydney is currently dealing with a widespread asbestos-contaminated mulch investigation, with 45 locations - including potentially six schools - contaminated with bonded asbestos that was mixed in with garden mulch.

Since investigation into the mulch began, most identified sites have been found with the much lower risk bonded asbestos, while two have been found to include friable asbestos, which poses a much greater health risk to the community.
