Coral bleaching is a process where the coral animal expels the algae that live in its tissues, causing its white skeleton to become visible through its translucent flesh. It is triggered by changes in water temperature, with extreme marine heatwaves killing corals outright. Coral bleaching has become a growing concern for Australia, with the Great Barrier Reef, the world's largest coral reef system, experiencing consecutive years of coral bleaching. To combat this, the Australian government has announced a A$1 billion plan to address issues such as poor water quality and agricultural runoff. Additionally, there are calls for the government to adopt reef-safe climate policies, including cutting climate pollution and stopping approvals for new fossil fuel projects, as Australia is one of the world's largest exporters of fossil fuels, contributing to global warming and marine heatwaves.

The Australian government has committed \$1 billion to help the Great Barrier Reef
The Australian government has committed $1 billion to help the Great Barrier Reef, which is the world's biggest coral reef system. This funding is intended to address the issues that the reef is facing, such as poor water quality caused by floods and agricultural and industrial runoff.
The Great Barrier Reef has experienced widespread coral bleaching for the fourth time in seven years, with 2024 and 2025 seeing consecutive years of coral bleaching for the second time. Coral bleaching is caused by rising ocean temperatures, with extreme marine heatwaves killing corals outright. Climate change is the greatest threat to the Great Barrier Reef, and coral reefs worldwide, and the gaps between bleaching events are becoming too short to allow the reefs to recover.
The Australian government's $1 billion plan to help the Great Barrier Reef does not address the primary threat to the reef: climate change. Australia is the world's third-largest exporter of fossil fuels, which are the main cause of the unprecedented marine heatwaves that are bleaching coral reefs. The Australian Marine Conservation Society has stated that the Australian government must do more to combat climate change if the Great Barrier Reef is to be saved.
To effectively combat coral bleaching, the Australian government must adopt reef-safe climate policies, including stopping approvals for new fossil fuel projects and cutting climate pollution. The Queensland government has demonstrated leadership in this area by committing to cut climate pollution by 75% over the next decade, and it is hoped that the Australian government will follow suit.

The gaps between these events are shortening, hindering the reef's ability to recover fully.
The Queensland government's commitment to reducing climate pollution is a crucial step in addressing this issue. By cutting pollution, the government aims to mitigate the climate-driven events that have damaged the reef. This includes addressing record rainfall and flooding in Queensland, which have been identified as contributing factors to coral bleaching in central and northern areas. The government's target of a 75% reduction in climate pollution over the next ten years demonstrates its recognition of the urgency of the situation and its willingness to take decisive action.
Additionally, the Queensland government's leadership in this area sets a precedent for other states and political parties to follow suit. By prioritising the protection of the reef, the government is sending a strong message about the importance of bipartisan support for reef-safe climate policies. This includes not only cutting climate pollution but also reevaluating the approval of new fossil fuel projects, as Australia's significant fossil fuel exports have been identified as a contributing factor to global marine heatwaves and, consequently, coral bleaching.
The Queensland government's commitment to cutting climate pollution by 75% over the next decade is a promising development in the fight to save the Great Barrier Reef. By taking responsibility for its impact on climate change, the government is taking a crucial step towards preserving this invaluable ecosystem and the diverse species that call it home. This decision sets a precedent for other regions and underscores the need for immediate and collective action to address the pressing environmental challenges posed by climate change and coral bleaching.

The Australian government must stop approving new fossil fuel projects
Coral bleaching is a process where the coral animal expels the algae that live in its tissues and give it its colour and nutrients. Without the algae, the coral's white skeleton becomes visible through its translucent flesh, giving it a bleached appearance. Coral bleaching is triggered by rising ocean temperatures, which are caused by climate change.
The Great Barrier Reef, the world's biggest coral reef system, has experienced widespread coral bleaching in the past two decades, with the fourth global bleaching event occurring in 2024. This has been driven by global heating and marine heatwaves, which are becoming more frequent and severe due to increasing levels of atmospheric greenhouse gases. The reef has also been impacted by flooding from record rainfall and discharge of freshwater due to extreme weather events.
As a major exporter of fossil fuels, Australia has an outsized impact on climate change and, by extension, global coral bleaching. Australia is the world's third-largest exporter of fossil fuels and one of the largest coal and gas exporters, contributing 5% of the world's greenhouse gas emissions when accounting for fossil fuel exports. Despite this, the Australian government has continued to approve new fossil fuel projects and provide subsidies for coal and gas exports.
To effectively combat coral bleaching and protect the Great Barrier Reef, the Australian government must stop approving new fossil fuel projects. This includes ending subsidies and other support for the fossil fuel industry. Instead, the government should focus on transitioning to renewable energy sources and reducing emissions in line with global efforts to limit warming to 1.5 degrees Celsius, a critical threshold for coral reefs. The Queensland Government has already demonstrated leadership in this area by committing to cut climate pollution by 75% over the next decade.
Additionally, the Australian government should adopt reef-safe climate policies, such as cutting climate pollution by 90% by 2035, as recommended by the Australian Marine Conservation Society. This includes improving water quality by addressing issues such as agricultural and industrial runoff. By taking these steps, the Australian government can play a crucial role in mitigating climate change, protecting the Great Barrier Reef, and preserving the $6.4 billion tourism industry and 64,000 jobs that depend on it.
