Newcastle City Council is refurbishing the pavilion at Merewether Ocean Baths and repairing erosion to the sea wall to the north of Merewether Surf House.
A new ramp will be built to improve access to the Depression-era bathers pavilion while the sea wall between Merewether Surf House and the surf club will be rebuilt to preserve beachside infrastructure for future generations.
"Council officers will be managing the seawall repairs and a general overhaul of the pavilion over the next few months," Lord Mayor Nuatali Nelmes said.
"The latest maintenance work is part of the ramped-up effort to address Newcastle's ageing infrastructure.
"Maintenance of the city's great coastal facilities is a constant for us. Stabilising cliffs and sea walls and maintaining run-down structures like the pavilion are just as important as providing new attractions and updates, like Bathers Way and various park upgrades."
The 81-year-old pavilion will get new roofing, gutters and downpipes, and repairs will be made to masonry, brickwork, windows and railings.
Plumbing, carpentry and electrical work will also be carried out before the finishing touches are added later in the year.
The seawall between Merewether Surf Club ramp and the shade structure below Merewether Surf House is also being reinforced after last year's super storm revealed wear and tear.
"Damage to this section of seawall was revealed during the April 2015 storms," Cr Nelmes said.
"Rehabilitation work is required to ensure the wall's long-term stability.
"Construction work includes partial demolition of the existing structure, construction of a new stepped wall and rebuilding the pathway to provide better amenity and access and improve safety along that stretch.
The works begin this week and are expected to be completed by summer.
During the work the baths will be fully functional with amenity sheds providing toilets, change rooms, showers and a temporary space for lifeguards.
Newcastle Ocean Baths are currently closed to allow annual sand removal work and storm damage repairs, which are expected to be finished by Sunday 21 August.
