The UNESCO World Heritage Committee has repeatedly identified land clearing as a key threat to the Great Barrier Reef, warning that continued degradation could place the Reef on the World Heritage “in Danger” list.

Queensland, Australia, is one of the world’s worst deforestation hotspots, with approximately 323,000–332,000 hectares of woody vegetation cleared every year. Alarmingly, nearly half of this clearing occurs within Great Barrier Reef catchment areas, with some studies estimating over 140,000 hectares annually in these critical regions alone. A significant proportion of this destruction involves remnant vegetation, meaning ecosystems that had never previously been cleared or closely resemble natural forest conditions.

Even more concerning, more than 80% of this clearing occurs on land exempt from Queensland’s vegetation laws, making it legally permissible under current loopholes. Approximately 77% of clearing is classified as “Category X” land, meaning it does not require a permit. These exemptions severely weaken the effectiveness of environmental protections, allowing land clearing to continue to occur at a catastrophic scale with barely any oversight. This continues despite reforms intended to reduce deforestation.

The consequences of this land clearing extend far beyond the forest itself, and directly impact the Great Barrier Reef. This is because the removal of native vegetation leaves soils exposed and highly vulnerable to erosion. Thus, during rainfall events, sediment, nutrients, and agricultural chemicals are washed into river systems that flow directly into the Reef. In extreme cases, the volume of sediment entering reef waters has been compared to hundreds of thousands of truckloads of soil, significantly degrading water quality.

This pollution causes smothering of coral reefs, reduced light penetration needed for coral and seagrass growth and declining reef resilience and water quality. Sediment and nutrient pollution also contribute to increased outbreaks of crown-of-thorns starfish, which feed on coral, reduced coral recovery following bleaching events and degradation of seagrass habitats essential for dugongs and green sea turtles.

On top of that, deforestation also increases the impacts of climate change on coral bleaching by weakening the reef’s ability to recover. Poor water quality reduces resilience after heat stress events, placing additional pressure on an already fragile ecosystem.

Not only is the biodiversity in the reef affected by deforestation, but so is the land ecosystem of Queensland. Queensland’s native forests support exceptionally rich biodiversity, including many threatened species such as koalas, greater gliders, and red goshawks, along with countless reptiles, amphibians, and invertebrates.

Deforestation leads to loss of remnant habitat critical for endangered species survival, fragmentation of ecosystems and reduced genetic diversity and increased extinction risk for already vulnerable species

Across Australia, it is estimated that tens of millions of native animals are affected annually by deforestation.

But now we have the chance to prevent all of this. Australia is currently at a critical policy crossroads. Proposed federal nature law reforms and ongoing state policy debates will determine the future of land clearing regulation for decades to come. Without stronger protections, millions of hectares of native vegetation remain at risk. Conservation organisations warn that the key question is whether Australia will continue to allow regulatory loopholes to enable deforestation, or instead implement stronger national standards that protect sensitive ecosystems such as Great Barrier Reef catchments.

This petition supports a campaign to protect Australia’s remaining native forests and the iconic Great Barrier Reef from further destruction. It will be submitted to the Queensland Government, calling for urgent legislation to close these loopholes and stop land clearing on currently exempt areas under Queensland vegetation laws.

Together, we can push for stronger environmental protections that safeguard Australia’s unique ecosystems for future generations.
