New documents show NSW Health rejected government advice to reduce the blood lead level (BLL) threshold for children in Broken Hill from 5 micrograms per decilitre (5μg/dL) to 3.5μg/dL. The Department of Premier and Cabinet had recommended this change to align with international standards and protect more children. Data shows 67% of children and over 90% of Aboriginal kids in Broken Hill would qualify for help under the 3.5 level. NSW Health argued it could not "recommend a change in level for one area in isolation" and warned of "unintended privacy consequences." Internal notes admit "there is no safe level of lead," and even 3.5μg/dL can cause "reduced IQ and attention span, learning disabilities, hyperactivity, behavioural problems, impaired growth and hearing loss." Greens MP Cate Faehrmann, who obtained the documents, called the situation a "national disgrace" and said government funding to help affected kids was "just pathetic." NSW has used 5μg/dL as the action point since 2016, but officials admit this is currently treated as "safe," though it is not. Experts say Broken Hill’s lead contamination comes mainly from mining dust, not old paint. A 2019 report buried by NSW EPA showed 49% of children and 76% of Indigenous children had blood lead above 5μg/dL, with mines as the main source. Internal emails reveal NSW Health tried to remove recommendations to lower the threshold in a 2023 draft briefing. Critics warn delays and lack of resources hamper response efforts. At a 2024 expert panel meeting, concerns were raised about limited capacity and unsustainable funding to help all children above 5μg/dL. NSW Health says it continues free screening for kids under five and is improving prevention programs. Government funding has exceeded $20 million since 2015 for lead programs in Broken Hill. Faehrmann demands urgent funding for house upgrades, health support, strict mine pollution rules, and careful use of mining royalties for the affected community.
