Australia flood and sea-level rise risks

Overview

Australia faces escalating economic and structural threats from flooding and rising sea levels. While initial assessments identified over two million homes exposed to flood risks, recent research from the University of Melbourne, the Australian National University, and the Climate Council provides more specific projections for coastal inundation.

A report titled ‘Rising Seas, Rising Bills’ warns that by 2100, rising sea levels and coastal flooding could threaten approximately 267,000 to 268,000 properties and two million hectares of land. The total economic impact is estimated to reach $855 billion, comprising $274 billion in property damage and $580 billion in losses to agricultural and other lands. Scientists predict sea levels will rise by at least 14 centimeters by 2050.

Regional impacts vary: Queensland faces the highest number of at-risk properties (over 93,000), followed by New South Wales. Western Australia is projected to suffer the greatest economic losses, estimated at $230.5 billion. Impacted land includes 619,000 hectares of farmland, 379,000 hectares of parks and recreation areas, and 23,000 hectares of critical infrastructure.

New modeling published in Scientific Reports suggests that if greenhouse gas emissions continue to increase, the situation could become significantly more severe. Under this scenario, the number of at-risk properties could rise to approximately 720,000, affecting 3.7 million hectares of land with potential economic losses escalating to $1.91 trillion.
