Council infrastructure services general manager Simon Drew said about 1.5m of sand had been deposited back on the beach in recent weeks, helped by some easterly swells.
The sand had now almost covered sandbags placed in front of sand dunes at Middle Beach in September, to try to protect the dunes from erosion.
Up to 13m of sand had been stripped from the area in August, raising fears an old landfill buried behind the dunes, under nearby Kettle Park, could be exposed.
Mr Drew said the situation was considered ''stable'' for now, following the return of sand, although the area remained a ''dynamic environment''.
Council staff were also finalising a plan which would ensure wide public consultation on the future for Ocean Beach, which stretches from St Clair to Lawyers Head, he said.
The consultation would consider what people wanted the area to be like over the next 100 years, together with the various options and costs that could achieve that, he said.
Those options would include reinstating one or more sand groynes in the area, as advocated by newly elected city councillor Jules Radich, he said.
''We'll go through all of those options with the community and assess those against what their values for the beach are and what success looks like.''
The plan was to have the work on options and costs completed in a year, which would then be considered as part of the council's next long-term plan process in 2021, he said.
