Byron Bay's famous beach has almost disappeared
The area is being badly hit by rain and wind, with the king tides causing severe coastal erosion.
The beach has been completely covered with water, with fallen trees along the coast also causing issues.
One man tried to walk along the partially smashed walkway as it collapsed in the ocean.
He fell - but did not appear to be hurt.
Trees are coming down, and the king tide is expected to just about hit its peak.
Sandbags are being used to try and protect businesses on the coast, including Beach Restaurant, which remained open despite the battering.
Owner Ben Kirkwood said flood defences installed recently were doing their job.
"I would say if it wasn't for the wall we wouldn't be here right now. It's doing its job. Thank goodness it got installed when it did," he told Today.
"We're a sheltered area where we are getting a lot of onlookers coming to watch the show.
"Down the other area of the beach the Main Beach it's taking a hammering."
Mr Kirkwood said in June this year, he estimates around 18 metres of sand dunes were lost when high tides smashed the area.
There are also multiple flood warnings for rivers in the area too, including the Tweed, Brunswick and Wilsons Rivers, with warnings the rain will continue.
Further north, the Gold Coast is also being battered by rain which is causing flash flooding.
Brisbane, especially Logan and Ipswich, are also being affected.
