Draft National Environmental Standard (Matters of National Environmental Significance) 2025

5 February, 2026
Some of Australia’s most precious places are imperilled by inaction on threatening processes. For example, the corals reefs of the Great Barrier Reef Marine Park are threatened by nutrient-rich run-off, the sensitive alpine vegetation of the Tasmanian Wilderness World Heritage Area is threatened by invasive deer, the rich cultural and ecological values of Uluru-Kata Tjuta […]

Invasive Species Council Submission – Draft Offsets Standard – Jan 2026

5 February, 2026
Offsets have generally failed to compensate for environmental damage not otherwise avoided or mitigated. But done well, offsets can present an opportunity to protect habitat or areas under imminent threat – from development or invasive species – or to restore the environment above and beyond the level of an approved impact, including at a landscape […]

A Living Legacy: Invasive Species Actions for South Australia

5 February, 2026
According to the South Australia State of the Environment Report 2023, invasive species remain a primary driver of biodiversity decline. Since the 1960s, they have cost the national economy more than $390 billion in management and impacts. The report highlights critical threats on Kangaroo Island, in regional and pastoral areas, and on Country. It also […]

Algal blooms in South Australia

6 October, 2025
In this submission we raise the question of whether Karenia mikimotoi – or the strain causing the algalbloom in South Australia – is native or introduced. There appears to be no published evidence to support arecent assumption that K. mikimotoi is native and that the bloom is ‘naturally occurring’. Understanding whether K. mikimotoi is native […]

From Lab to Landscape: Transforming Australia’s approach to invasive animals through coordinated mission-driven innovation

6 October, 2025
Invasive vertebrates are the biggest driver of animal extinctions in Australia and imperil more than 500 threatened species while causing massive landscape degradation. Despite some successes – particularly island eradications and fenced havens – most threats remain highly potent. Current management efforts are often fragmented, thinly spread, under-funded, short term and ineffective.  Evidence from island […]

Your gift is a lifeline for nature.

Our protected areas are being trashed, trampled, choked and polluted by an onslaught of invaders. Invasive species are already the overwhelming driver of our animal extinction rate, and are expected to cause 75 of the next 100 extinctions.

But you can help to turn this around and create a wildlife revival in Australia. 

From numbats to night parrots, a tax-deductible donation today can help defend our wildlife against the threat of invasive weeds, predators, and diseases.

As the only national advocacy environment group dedicated to stopping this mega threat, your gift will make a big difference.

A silent crisis is unfolding across Australia. Every year, billions of native animals are hunted and killed by cats and foxes. Fire ants continue to spread and threaten human health. And the deadly strain of bird flu looms on the horizon. Your donation today will be used to put the invasive species threat in the media, make invasive species a government priority, ensure governments take rapid action to protect nature and our remarkable native wildlife from invasives-led extinction, death and destruction.

    Dear Project Team,

    [YOUR PERSONALISED MESSAGE WILL APPEAR HERE.] 

    I support the amendment to the Kosciuszko National Park Wild Horse Heritage Management Plan to allow our incredible National Parks staff to use aerial shooting as one method to rapidly reduce feral horse numbers. I want to see feral horse numbers urgently reduced in order to save the national park and our native wildlife that live there.

    The current approach is not solving the problem. Feral horse numbers have rapidly increased in Kosciuszko National Park to around 18,000, a 30% jump in just the past 2 years. With the population so high, thousands of feral horses need to be removed annually to reduce numbers and stop our National Park becoming a horse paddock. Aerial shooting, undertaken humanely and safely by professionals using standard protocols, is the only way this can happen.

    The government’s own management plan for feral horses states that ‘if undertaken in accordance with best practice, aerial shooting can have the lowest negative animal welfare impacts of all lethal control methods’.

    This humane and effective practice is already used across Australia to manage hundreds of thousands of feral animals like horses, deer, pigs, and goats.

    Trapping and rehoming of feral horses has been used in Kosciuszko National Park for well over a decade but has consistently failed to reduce the population, has delayed meaningful action and is expensive. There are too many feral horses in the Alps and not enough demand for rehoming for it to be relied upon for the reduction of the population.

    Fertility control as a management tool is only effective for a small, geographically isolated, and accessible population of feral horses where the management outcome sought is to maintain the population at its current size. It is not a viable option to reduce the large and growing feral horse population in the vast and rugged terrain of Kosciuszko National Park.

    Feral horses are trashing and trampling our sensitive alpine ecosystems and streams, causing the decline and extinction of native animals. The federal government’s Threatened Species Scientific Committee has stated that feral horses ‘may be the crucial factor that causes final extinction’ for 12 alpine species.

    I recognise the sad reality that urgent and humane measures are necessary to urgently remove the horses or they will destroy the Snowies and the native wildlife that call the mountains home. I support a healthy national park where native species like the Corroboree Frog and Mountain Pygmy Possum can thrive.
