Before and after pictures of Australia’s east coast show the true scale of devastation caused by Tropical Cyclone Alfred. What was once a paradise for surfers, with golden, sunlit sands, became a battleground as waves as high as ‘three or four-storey buildings’ slammed into the coastline.

Residents are stacking sandbags to protect low-lying properties ahead of a tropical cyclone that is forecast to become the first in 51 years to hit the Australian east coast near Brisbane, the nation’s third-most populous city.

Millions of residents along Australia’s eastern coast are bracing for the arrival of a very slow-moving storm, the most southerly tropical cyclone to threaten the region in more than 50 years.
