Australia is one of the world's most biodiverse countries — home to unique flora and fauna found nowhere else on Earth. It also has one of the worst records of species extinction of any developed country, with habitat loss, invasive species, and climate change threatening extraordinary ecosystems. Environmental philanthropy in Australia funds conservation, restoration, advocacy, and the science that underpins effective environmental management.
Biodiversity crisis
Australia has lost more mammals to extinction in the last 200 years than any other country. Habitat loss — primarily from land clearing, agricultural expansion, and urbanisation — is the primary driver. Invasive species (feral cats, foxes, rabbits, cane toads) cause enormous additional harm to native wildlife. The 2019-20 Black Summer bushfires killed or displaced an estimated three billion animals.
Great Barrier Reef
The Great Barrier Reef — the world's largest coral reef system — is under severe threat from warming ocean temperatures (coral bleaching), water quality degradation, and crown-of-thorns starfish outbreaks. Reef restoration and protection is a major environmental philanthropy area.
Marine environment
Australia has the world's third largest Exclusive Economic Zone. Marine conservation — protecting marine habitats, reducing fishing bycatch, addressing marine pollution — is an important but relatively underfunded environmental area.
Freshwater systems
Australia's inland rivers and wetlands — including the Murray-Darling Basin — are under pressure from water extraction, pollution, and climate change. Freshwater conservation philanthropy is growing.
Climate change
Australia is highly vulnerable to climate change — through increasing bushfire frequency and intensity, coral bleaching, coastal inundation, drought, and extreme heat. Climate philanthropy in Australia funds both mitigation advocacy and adaptation.
Australian Government environmental programmes
Federal environment funding includes: National Heritage Trust programmes, threatened species recovery, environmental water, and Reef Trust. State and territory governments manage significant conservation programmes — including national parks, vegetation management, and biodiversity offsets.
Major environmental funders
The Ian Potter Foundation: arts, science, and environment; significant Australian conservation investment.
Paul Ramsay Foundation: significant environment investment alongside health and education.
Minderoo Foundation: environment focus including Great Barrier Reef, land clearing, and climate.
Pew Charitable Trusts: significant Australia investment in marine reserves, land clearing, and sustainable fisheries.
The Nature Conservancy Australia: major conservation land protection and restoration.
WWF-Australia: national conservation campaigns and local conservation projects.
Australian Conservation Foundation: environment advocacy and grassroots organising.
Grosvenor: freshwater, coastal, and urban environment.
State-based trusts: environmental trusts in New South Wales (NSW Environmental Trust), Victoria, and other states fund local conservation.
Threatened species recovery
Australia's threatened species — koalas, Tasmanian devils, bilbies, quolls, orange-bellied parrots, and hundreds more — need targeted recovery action: captive breeding, habitat protection, predator control, and population monitoring. Grants for threatened species recovery address the biodiversity crisis directly.
Predator control
Feral cats and foxes kill billions of native animals annually. Landscape-scale predator control — using fencing, trapping, baiting, and lethal control — protects native wildlife populations. Grants for predator control programmes at significant scale have major conservation impact.
Habitat protection
Protecting native habitat — through property purchase, conservation covenants, and legal protection — preserves the ecological foundation for biodiversity. Private land conservation — through conservation agreements with landholders — protects significant areas of habitat outside the national park estate.
Reef conservation
Great Barrier Reef restoration — coral gardening, crown-of-thorns control, improved water quality — requires significant ongoing investment. Climate change adaptation for the reef requires both local action (water quality improvement) and global action (emissions reduction advocacy).
Marine protected areas
Expanding and effectively managing marine protected areas — the ocean equivalent of national parks — protects marine biodiversity. Australian Greens Senators has advocated for larger marine reserves; philanthropic support for marine conservation advocacy and science strengthens this case.
Landcare and community conservation
Landcare — community groups working together for sustainable land management — has transformed Australian conservation. Landcare groups restore native vegetation, control weeds and pests, and monitor ecosystems across millions of hectares. Grants for Landcare groups and regional conservation networks are high-value.
Environmental advocacy
The most cost-effective environmental philanthropy often funds advocacy — for stronger environmental laws, better enforcement, increased government conservation investment, and policy reform. Environmental advocacy philanthropy in Australia has produced significant conservation outcomes, including the creation of marine reserves and restrictions on land clearing.
Science-based priorities
Environmental conservation is a field with strong science on which interventions achieve the greatest biodiversity returns. Funders who engage with conservation science — through scientific advisors, evidence reviews, and partnerships with research institutions — make better decisions about where conservation investment has the greatest impact.
Climate change as threat multiplier
Climate change amplifies all other threats to Australian biodiversity. Environmental philanthropy that addresses climate change — through clean energy transition, emissions reduction advocacy, and climate adaptation — produces conservation co-benefits.
