The severe storms that have battered the east coast have left several beaches covered in sea foam - but there's a good reason to steer clear of the phenomenon. So far, the bulk of the foam has turned up on beaches in the Northern Rivers region of NSW and on the Gold and Sunshine coasts, attracting crowds of curious locals. The foam also went viral across the globe after a local Byron Bay woman interrupted a live weather update to search for her missing dog, Hazel, who was later rescued from the mess.

Sea foam often forms when strong winds and large waves whip up the cresting waves. pic.twitter.com/KSmREu2ADs— BBC Weather (@bbcweather) December 14, 2020
