Learn moreAbout Mirrabooka's Climate Risk Profile
Mirrabooka, a suburb in Perth, Western Australia, is increasingly vulnerable to the impacts of climate change. The primary risks include increased heatwave frequency and intensity, moderate flooding potential, and a moderate bushfire risk due to surrounding vegetation.
The risk of heatwaves is a major concern. Rising global temperatures, combined with the urban heat island effect, are projected to lead to more frequent and severe heatwaves in Mirrabooka. This poses a significant threat to public health, especially for vulnerable populations.
Flooding is another area of concern. Heavy rainfall events can overwhelm drainage systems, leading to localized flooding. Climate change is expected to increase rainfall intensity, further exacerbating this risk. Aging infrastructure also contributes to the problem.
Bushfire risk is moderate due to the presence of nearby bushland and parks. Hot, dry summers create conditions conducive to fire ignition and spread. While not as severe as some other areas, residents should still be prepared for potential bushfire threats.
Coastal risks are minimal due to Mirrabooka's inland location. Sea level rise and coastal erosion are not significant concerns for this suburb.
