Dangerous surf generated by Tropical Cyclone Linda has forced the closure of beaches along Queensland's southeast coast.
The category one cyclone is about 850km northeast of Brisbane and is tracking towards the Queensland coast, but is not expected to make landfall.
The Bureau of Meteorology expects Linda to be downgraded to a low pressure system as it loses strength on Wednesday morning.
Despite that, lifeguards have closed all Gold Coast beaches due to hazardous conditions.
Several Sunshine Coast beaches including Marcoola, Coolum and Maroochydore have also been closed.
"It's really important to remember that we don't just close beaches on a whim," Surf Lifesaving Queensland's Jason Argent said.
"If a beach is closed it's because lifeguards deemed the conditions too dangerous, and allowing members of the public into the water would put their lives at considerable risk."
The bureau warns gale force winds over offshore waters will produce large swells along exposed parts of the coastline over the next two days.
It's expected dangerous surf conditions and beach erosion will persist until Thursday.
Authorities are also warning of very high tides on Thursday morning.
