Treachery is a statutory offence in Australia. There was also an unrelated statutory offence bearing that name in the United Kingdom, but it has been abolished. Both of these offences were derived from or inspired by the related offence of treason. The name treachery was chosen because it is a synonym for treason.
The offence is created by section 24AA of the Crimes Act 1914.
See the Treachery Act 1940.
