Our recent biosecurity mistakes

Our Work  |  Biosecurity

Australia is far from being a clean, green country when looking at our record of keeping our native wildlife safe from invasive species from beyond Australia. In 1999, the book Feral Future documented over two hundred years of the deliberate and accidental introduction of invasive species. However our track-record since then remains poor.

Here we document the major failings in keeping new species from establishing in the wild.
