Every five years, the Great Barrier Reef Marine Park Authority publishes an Outlook Report that examines the Great Barrier Reef’s health, pressures, and likely future.

The report is required under Great Barrier Reef Marine Park Act 1975 (section 54) and aims to provide a regular and reliable means of assessing reef health and management in an accountable and transparent way.

The 2019 report is the third comprehensive report in the series, and identifies the Great Barrier Reef Region still faces significant pressures, ranging in scale from local to global.

The report finds the greatest threat to the Reef is still climate change. The other main threats are associated with coastal development, land-based run-off, and direct human use (such as illegal fishing).

Since 2014, management initiatives and local actions have demonstrated positive outcomes for less complex and small scale activities, such as ports management and tourism.

However, achieving outcomes on the ground continues to be difficult for complex and spatially broad threats, such as climate change and land-based run-off.

Significant global action to address climate change is critical to slowing the deterioration of the Reef’s ecosystem and heritage values and supporting recovery. Such actions will complement and greatly increase the effectiveness of local management actions in the Reef and its catchment.
