Climate Hazard Breakdown for Petrie

increasing

Flood

65/100

Petrie is located near the North Pine River and is susceptible to flooding from heavy rainfall events. Climate change is expected to increase the intensity of rainfall, leading to more frequent and severe flooding.

Key drivers:

·Increased rainfall intensity
·Sea level rise affecting riverine flooding

increasing

Bushfire

40/100

Parts of Petrie are located near bushland areas, increasing the risk of bushfires, particularly during dry periods. Climate change is expected to increase the frequency and intensity of bushfire weather.

Key drivers:

·Increased frequency of heatwaves
·Drier vegetation

About Petrie's Climate Risk Profile

Petrie, Queensland, is a suburb that is increasingly vulnerable to the impacts of climate change. The primary risks are associated with flooding from the North Pine River, exacerbated by increased rainfall intensity. Heatwaves are also a growing concern, with rising average temperatures and more frequent extreme heat events expected in the future.

The suburb's proximity to bushland areas contributes to a moderate bushfire risk, particularly during dry periods. While Petrie is not directly exposed to coastal hazards, the broader region is susceptible to sea level rise and storm surge, which can indirectly affect the suburb.

Climate projections indicate that these risks will intensify in the coming decades. By 2030 and 2050, Petrie is likely to experience more frequent and severe flooding, more intense heatwaves, and a higher risk of bushfires. These changes will have significant implications for the community, infrastructure, and environment.

Adapting to these changes will require a coordinated effort from residents, businesses, and local government. Measures such as improving flood defenses, implementing heatwave management plans, and reducing bushfire fuel loads will be essential to protect the suburb from the worst impacts of climate change. Individual actions, such as preparing for emergencies and conserving water, can also make a significant difference.
