For many people, the most visible impact of Cyclone Alfred was the damage big waves and storm surge did to their local beaches.
Beaches in southeast Queensland and northeast New South Wales are now scarred by dramatic sand cliffs, including the tourist drawcard of Surfers Paradise.
Sand islands off Brisbane – Bribie, Moreton and North Stradbroke – protected the city from the worst of the storm surge. But they took a hammering doing so, reducing their ability to protect the coastline.
The good news is, the sand isn’t gone forever. Most of it is now sitting on sandbars offshore. Over time, many beaches will naturally replenish. But sand dunes will take longer. And there are areas where the damage will linger.
