Before COVID-19, global surf tourism spending was estimated at up to A$91 billion per year. And since the start of the pandemic, demand for surfing has boomed as people increasingly turn to outdoor activities.

Changes to the coastline – such as from sea walls and groynes – can dramatically reduce the quality of surfing waves.
