FLOOD modelling work in which Mandurah is among a number of areas increasingly vulnerable to the effects of rising sea levels is no surprise to the Peron Naturaliste Partnership.

The report, released last week by Coastal Risk Australia, claimed that if sea levels continued to rise around Australia by 74 centimetres by the end of the century, Mandurah and many other places could be inundated.

Among areas likely to be underwater would be the eastern and western foreshores, Keith Holmes Reserve, most of Yunderup, parts of Halls Head and the Forrest Highway.

Mandurah’s unique canal lifestyle could also be under threat.

The Peron Naturaliste Partnership, which includes nine coastal local government authorities, including the City of Mandurah, has been working to identify potential coastal risks from rising sea levels and a changing climate since 2011.

It has undertaken hazard mapping for coastal erosion and flooding, economic modelling, identified potential adaptation options and hosted information sessions and workshops.

Chairman John McCallum said the Partnership was established to tackle the issue.

“We are taking a collaborative approach to not only identify vulnerable areas and risks but we are taking action so we can empower and build a resilient community,’’ he said.

He said the Partnership had engaged UWA to monitor the coastline for a better understanding of current and future areas vulnerable to erosion and flooding.

The Coastal Risk Australia report said parts of Perth, Bunbury, Rockingham and Busselton would also be some of the worst affected parts of Australia.

More than 80 per cent of Australians live near the coast.
