Commencement
Commencement
The commencement date, which is also known as the 'date of operation', is the date upon which a particular piece of legislation comes into force. The commencement date may be:
- retrospective (in the past)
- upon receiving Royal Assent from the Govenor or Governor-General
- at a proclaimed date (in the future)
- in relation to another piece of legislation
- the default date of 28 days after receiving Royal Assent
Sometimes different sections of an Act can commence at different times.
Commencement dates are published in the Government Gazette and also appear in the Notes sections of Reprinted Acts.
