King tides and powerful surf are causing further erosion to cyclone-damaged Gold Coast beaches, with a lifeguard tower toppling into the sea at Surfers Paradise.

It is the second tower to be affected after ex-Tropical Cyclone Alfred hammered the city's coastline, washing away four million cubic metres of sand.

The fresh damage comes as a massive effort is already underway to ready Gold Coast beaches for the Easter holiday season.

A dredging barge for beach restoration works is set to be put to work tomorrow at a cost of $10 million.

Gold Coast disaster coordinator Mark Ryan said the lifeguard tower in the tourist hotspot had been damaged after three nights of high tides reaching 1.8 metres.

"We saw some fairly significant activity again on the beaches last night and that's going to continue into today," he told ABC Gold Coast.

He said the area near the structure at Surfers Paradise would continue to be a "hazard area" as the Bureau of Meteorology warns of large and powerful surf conditions in the coming days.

"We've still got another high tide tonight before it sort of starts to drop from tomorrow," Mr Ryan said, adding council crews were inspecting the tower and putting a safety plan in place for beachgoers.

"They'll have a plan in place … they have done some correction work already to that area.

"The sustained 1.8 [metre] tides certainly test our coastline … plus [there is] just so much water in our catchments right now."

Mr Ryan said council staff had been managing requirements on and off the beaches after the Gold Coast was hit with more wild weather last weekend.

"Our contractors, our maintenance staff, our construction staff, if you think, in the last week, [they] have gone from recovering the beaches, they're still out in the suburbs picking up the trees and there is still a deal of work," he said.

"They then dropped everything. They opened sandbags again last week for the rain event … they then flicked into closing roads and then they're back into recovery mode.

"We'll continue to keep throwing everything at it … we've always said that this was going to be weeks and weeks of recovery in that early part, and we're committed to the longer-term, medium recovery work."

Acting Chief Lifeguard, Will Ashley said another lifeguard tower near The Spit was also damaged due to wild weather.

"It's not a common thing these towers to come over," he said.

"We did have the one go down during ex-Tropical Cyclone Alfred up near [tower] 42 there.

"They're so bottom heavy. It actually was quite a large cliff that had slid down there, and it just came down this cliff and landed on its concrete slab."
