Polygala myrtifolia, commonly known as Myrtle-leaf Milkwort, is an invasive coastal weed of South African origin that poses a serious threat to Australia's unique ecosystems. This fast-spreading weed has been rapidly invading our precious coastal dune systems from Western Australia to New South Wales, including Tasmania, Victoria, and South Australia. It is crucial that we take immediate action to prevent its further spread and protect our natural heritage.

Why is this important? Polygala myrtifolia thrives in coastal conditions, where it aggressively competes with native vegetation for sunlight, water, and nutrients. This competition results in the displacement of native plants, ultimately threatening local biodiversity. Furthermore, the weed’s rapid growth exacerbates erosion and reduces habitat availability for native fauna, further endangering Australia's coastal ecosystems.

Currently, Polygala myrtifolia is not listed as a Weed of National Significance (WoNS) nor is it a Declared Noxious Weed in most states and territories. Declaring it as such would lead to stricter control measures, prompt timely management responses, and help guide funding allocation aimed at eradication and control programs. Effective management not only requires identification and removal but also the restoration of affected areas to encourage the regrowth of native plant species.

Taking action against this invasive species is supported by numerous research studies and environmental observations. For instance, data from the Australian Invasive Species Council highlights Polygala myrtifolia’s impact on native plant and animal communities, clearly demonstrating the need for national recognition of this weed's priority status.

We urge the relevant environmental authorities at both the state and national levels to recognize the threat posed by Polygala myrtifolia by listing it as a Weed of National Significance (Commonwealth) and a Declared Noxious Weed (State). By doing so, we can implement nationwide measures to mitigate its impact and restore the balance of our coastal ecosystems.

Please sign this petition to demand immediate government action to protect Australia's natural environments from the destructive spread of Polygala myrtifolia.
