Please be reminded that in accordance with Section 6A of the Smoke-free Environment Act 2000 – Smoking is banned in spectator areas at public sports grounds and other recreational areas in NSW. However, smoking is only banned when an organised sporting event is being held (this includes training).
Major sporting facilities are included under the definition of a public sports ground and are required to comply with the law. Other outdoor sporting facilities, such as Local Council playing fields, are also covered by the law.
