The "Building and Construction Industry Security of Payment Act 1999" came into effect in New South Wales on 26 March 2000 and applies to all construction contracts commenced on or after that date. It is not possible to contract out of the legislation. Amendments to the Act made in 2013 are not retrospective, however, earlier amendments are. The Act does not apply to mining work, however, construction work ancillary to the operation of a mine is covered. The Act also does not apply to work undertaken for a resident owner within the meaning of the "Home Building Act 1989".
