Ten of Sydney's iconic eastern beaches, including Coogee, Maroubra and Clovelly, will become smoke-free zones after a motion to ban smoking on the beach was passed by the Randwick Council on Tuesday night.

The ban, which was proposed by Randwick Labor councillor Kathy Neilson and was carried on a show of hands at Tuesday night's council meeting, brings Randwick's beaches into line with Sydney's other popular beach spots, including Bondi beach and Manly beach.

No-smoke zone: Coogee Beach has banned cigarettes.

Manly, Waverly, Woollahra Councils have already banned smoking on the beaches in their districts.

The ban will come into effect after no-smoking signs are installed on the beaches in the coming weeks.
