The NSW Government will dedicate $83.6 million to managing its coastline in next month’s budget.

It is the biggest commitment of state funds to coastal management in about 40 years.

Planning Minister Rob Stokes says the funds will help councils make communities more resilient, and aid strategic land-use planning and coastal management reforms.

“The package of funding includes $69 million of new funding and the redirection of $14.6 million in existing coastal management spending, which is the most significant commitment of state funds to coastal management since the 1970s,” Mr Stokes said.

More than $63 million will be made available for councils to reduce exposure to coastal hazards such as beach erosion, inundation and cliff instability.

A further $9.5 million will help councils prepare coastal management programs in preparation for population growth and development demand.

State Treasurer Gladys Berejiklian says the funding commitment recognises that the coast is a vital economic zone.

She says a $7 million investment in statewide science and technical advice will help councils assess the vulnerability of coastal areas and prepare appropriate responses.

Councils can also apply for grants to implement actions identified in their coastal management programs.
