Wild seas whipped up by a tropical low in Queensland have forced the closure of all major metropolitan beaches.
Waves are at an average of two metres and are peaking at three metres, Surf Lifesaving NSW said. Beaches were closed progressively through the day as conditions worsen.
However, a Sutherland Shire spokeswoman said Wanda Beach remains open.
Thousands of surfers have taken advantage of the giant swell but swimmers have been warned to steer clear of the treacherous conditions.
Elsewhere in NSW, all beaches north of Nambucca Heads are closed, Surf Lifesaving NSW spokesman Brett Moore said.
As smh.com.au spoke to him, three lifeguards were sent into the seas to rescue about four surfers whose surfboards had been pulled from them in the pounding surf.
Mr Sylvester said inexperienced surfers were endangering themselves in the huge seas.
"There's so much volume in these waves, they are what we call a meaty wave ... When [the surfers] wipe out, their board gets whipped off."
The Bureau of Meteorology said the big swells were likely to continue until about Friday, because the tropical low was moving so slowly.
"It's what [surfers] dream of. It will be Christmas and New Year's for them to remember for a long time," forecaster Dave Williams said.
