Australia is facing an extinction crisis. Since European colonisation, we have lost more mammal species than any other continent. Many more teeter on the brink. The region spanning South East Queensland and Northern NSW—one of Australia's biodiversity hotspots—is home to numerous threatened species that require urgent protection.
Australia's Extinction Crisis
Understanding Threatened Species Classifications
Species are classified according to their extinction risk. Understanding these categories helps communicate the urgency of conservation needs.
Species Profiles
Koala
Phascolarctos cinereus
Once widespread across eastern Australia, koalas have suffered dramatic population declines due to habitat loss, vehicle strikes, dog attacks, and disease. In South East Queensland, populations have declined by over 50% in the past two decades.
Key Threats
Conservation Efforts
Habitat protection, wildlife corridors, hospital programs, disease research
Greater Glider
Petauroides volans
Australia's largest gliding marsupial, the greater glider depends on old-growth eucalypt forests with abundant tree hollows. Logging, fire, and climate change have caused severe declines, with populations crashing after the 2019-2020 bushfires.
Key Threats
Conservation Efforts
Old-growth forest protection, fire management, hollow retention
Eastern Curlew
Numenius madagascariensis
The world's largest shorebird, the eastern curlew migrates between Australia and Siberia. Populations have halved in the past 30 years due to habitat loss at stopover sites in Asia and development of Australian coastal wetlands.
Key Threats
Conservation Efforts
Wetland protection, international flyway agreements, disturbance management
Richmond Birdwing Butterfly
Ornithoptera richmondia
One of Australia's largest butterflies, the Richmond birdwing has lost much of its subtropical rainforest habitat. Its larvae also die when feeding on the introduced dutchman's pipe vine instead of native food plants.
Key Threats
Conservation Efforts
Rainforest restoration, vine removal, captive breeding
Regent Honeyeater
Anthochaera phrygia
Once abundant across south-eastern Australia, fewer than 400 regent honeyeaters remain in the wild. Habitat loss has been so severe that the species is forgetting its own songs, with males now mimicking other species.
Key Threats
Conservation Efforts
Captive breeding, habitat restoration, song tutoring programs
Southern Cassowary
Casuarius casuarius johnsonii
Australia's heaviest bird is a keystone species for rainforest ecosystems, dispersing seeds of over 200 plant species. With fewer than 5,000 remaining, they face ongoing threats from vehicles, dogs, and habitat loss.
Key Threats
Conservation Efforts
Habitat protection, road management, community education
Loggerhead Turtle
Caretta caretta
Loggerhead turtles face threats throughout their lifecycle, from nest predation to fishing bycatch. Australian populations are genetically distinct and critical for the species' global survival.
Key Threats
Conservation Efforts
Beach protection, nest monitoring, bycatch reduction, lighting controls
Grey-Headed Flying Fox
Pteropus poliocephalus
Essential pollinators and seed dispersers for native forests, grey-headed flying foxes have declined by over 30% due to habitat loss and heat-related mass mortality events that can kill tens of thousands in a single day.
Key Threats
Conservation Efforts
Camp protection, habitat restoration, heat event response
Why Species Become Endangered
Understanding the drivers of species decline is essential for effective conservation. In Australia, several factors combine to create particularly severe threats.
Habitat Loss
The single greatest threat to Australian wildlife is habitat destruction. Since European settlement, Australia has cleared over 40% of its forests and 90% of temperate woodlands. Clearing continues at alarming rates, particularly in Queensland, which has some of the highest land-clearing rates in the developed world.
Invasive Species
Australia's native wildlife evolved in isolation and is particularly vulnerable to introduced predators. Feral cats alone kill an estimated 1.7 billion native animals annually. Foxes, pigs, goats, and numerous invasive plants compound the threat.
Climate Change
Rising temperatures and changing rainfall patterns are already affecting wildlife. Species adapted to cool, moist conditions are being pushed to the edge of their tolerance. Extreme events like the 2019-2020 bushfires have catastrophic effects on already vulnerable populations.
Disease
Novel diseases can devastate populations. Chlamydia has severely impacted koala populations, while chytrid fungus has caused amphibian extinctions. Climate change may enable diseases to spread to new areas.
"What we are doing to the forests of the world is but a mirror reflection of what we are doing to ourselves and to one another."

Conservation Priorities for the Region
Effective conservation requires focusing resources on the most important actions. For South East Queensland and Northern NSW, priorities include:
Protecting Remaining Habitat
Preventing further habitat loss is the most critical action. This includes:
- Strengthening vegetation protection laws
- Expanding the protected area network
- Supporting private land conservation
- Protecting wildlife corridors
Managing Threats
Reducing key threats within existing habitat is essential:
- Feral predator control, particularly cats and foxes
- Weed management to protect native vegetation
- Fire management for fire-sensitive species
- Disease management programs
Recovery Actions
For the most threatened species, targeted recovery actions are needed:
- Captive breeding as insurance populations
- Translocation to establish new populations
- Genetic rescue to address inbreeding
- Habitat restoration in key areas
The Role of Tourism in Species Conservation
Tourism can be a powerful tool for endangered species conservation—or a significant threat. The difference depends entirely on how it is managed.
Tourism supports conservation by:
- Generating revenue that funds protection and recovery programs
- Building awareness among visitors who become conservation advocates
- Creating economic value for wildlife that justifies protection
- Providing employment for local communities in conservation-compatible activities
- Supporting research through citizen science and funding contributions
Tourism threatens endangered species when:
- Visitor numbers exceed what sensitive species can tolerate
- Access is permitted during critical breeding periods
- Infrastructure development destroys or fragments habitat
- Commercial pressure overrides conservation limits
Professional management ensures tourism delivers conservation benefits while preventing harm. This requires deep knowledge of the species present, their sensitivities, and the management actions needed to protect them.
