Residential strata buildings in NSW must have safety devices installed on all above ground windows following a new law brought in on 13 March 2018 to help protect children. As a result, windows which open and have a two metre or greater fall on the outside, and a 1.7 metre or less height on the inside, must be restricted to opening only 12.5cm. They must also meet a pressure test of 250 newtons/25.5kg of weight in pressure.
If an owner's corporation or individual fail to comply it could result in a fine. Around 50 children fall from windows or balconies in Australia every year.
