All beaches on Queensland's Gold Coast are closed but lifeguards will consider opening some southern areas later in the day.
Mayor Tom Tate says sand dredged from the Gold Coast Broadwater will be deposited south of Surfers Paradise, but not until conditions improve.
The chairwoman of the council's engineering committee, Daphne McDonald, says there has been no new erosion overnight.
"It takes some weeks for any of that sand movement to take place but that really depends on the weather conditions," she said.
"But our beaches are beautiful and I am sure once the sun comes out we will have all of our beachgoers back on the beaches again."
Meanwhile, more than 20 beaches on the Sunshine Coast are closed today due to severe erosion and rough surf.
Lifeguard Anthony King says only three beaches will be open.
"We've virtually got no beach at the moment," he said.
"We've got about 1.5 to two metres of really messy rough surf.
"The only locations that may be open today will be Mooloolaba, Noosa and Kings Beach and basically as well we've got a straight easterly wind and it's really strong, so messy and rough conditions today and there will be a lot of beaches closed today unfortunately."
Authorities on the Sunshine Coast have also begun to assess other damage from this week's drenching.
More than 200 millimetres has fallen in some parts in the past 48 hours and more rain is forecast for Friday.
Alan Rogers from the local disaster management group says pavements are crumbling and roads are riddled with potholes.
"Had some significant impact on our road network, the pavement, the amount of potholes," he said.
"The impact on the road network is such that the pavement starts to crumble and we start to see a lot of potholes emerging.
"That takes three to six months to really fully emerge, so we can't really cost the details of the event."
