King tides and extreme weather have reportedly eroded up to five metres from the Byron Bay shoreline, threatening businesses and damaging waterfront walkways.

Heavy rain lashed the coastline between northern NSW and south-eastern Queensland over Sunday, causing local waterways to surge and forcing locals to install sandbags around a beachfront restaurant.

Yesterday’s fears of severe coastal erosion were confirmed on Monday morning, with The Today Show‘s Hannah Sinclair reporting “We’ve seen the beach literally fall away… the beach is literally chipping away.”

“It has gone back at least three to five metres in twelve hours, that is how bad it is,” she added.

“We’re talking about Byron Bay, you know, one of Australia’s most iconic beaches, and this is the scene at the moment.”

Footage from the waterfront showed a damaged walkway collapsing below a man as he inspected the erosion. The Today Show reports he appeared to be unharmed.

The Bureau of Meteorology’s (BoM) severe weather warning remains in place for the coastal region spanning Tweed Heads to just above Taree, with residents advised to prepare for brutal winds and rain, along with “abnormally high tides and damaging surf.”

The BoM today issued a moderate flood watch alert, with residents of Murwillumbah, Tumbulgum, and Chinderah advised to watch out for rising waters over the next couple of days.

Speaking to the Sydney Morning Herald on Sunday, the Bureau of Meteorology’s Jonathan How said the ongoing storm is “the most significant rainfall event since February”.

The State Emergency Service has fielded more than 700 calls in relation to the weather system.

Stay safe out there, folks.
