Tell The Hills Shire to Stop Denying the Evidence.

The Hills Shire Council told us it does not use SGARs. Its own product list includes three: Generation First Strike (difethialone), Maki Blocks (bromadiolone), and Ditrac Blox (brodifacoum). These products accumulate in native wildlife through secondary poisoning. Send a direct email to the General Manager asking them to acknowledge the facts and phase out all SGARs.

Why This Matters

Three SGARs on the product list — and a denial that they're used at all.

Secondary poisoning of native wildlife

SGARs accumulate in the tissue of poisoned rodents and remain lethal for days. Native predators — powerful owls, wedge-tailed eagles, raptors, quolls, and antechinus — are exposed when they eat affected animals. Research led by Prof. Raylene Cooke and Assoc. Prof. John White at Deakin University has documented SGAR toxins in the livers of native predators across Australia.

Active regulatory review by the APVMA

The Australian Pesticides and Veterinary Medicines Authority is currently reviewing SGAR registrations following evidence of widespread non-target harm. Councils continuing to use these products risk being on the wrong side of an emerging regulatory shift.

Effective alternatives already exist

The Hills Shire Council already uses Selontra (colecalciferol) — a non-anticoagulant alternative with substantially lower risk to native wildlife. The safer option is already in operation. What is needed is a formal commitment to remove the three SGAR products from all council contracts and operations.

Councils that have already made the switch: Blue Mountains, Hornsby, Byron, Camden, Campbelltown, Inner West, Clarence Valley, Kiama, and Edward River have all implemented SGAR-free policies. The Hills Shire — a north-western Sydney LGA bordering Cattai National Park, Marramarra National Park, and significant Hawkesbury River bushland — has every reason to remove SGARs from its operations and align its internal practices with the evidence its own product list confirms.
