Australian Building Codes Board

The Australian Building Codes Board (ABCB) is a body that writes Australia's standardized building requirements, including the National Construction Code (NCC), WaterMark, and CodeMark. The ABCB is part of a joint endeavour by the Commonwealth, state and territory governments, and the country's plumbing and building industries.

The ABCB is "the authority responsible for building regulation in Australia". NCC regulations are revised every three years, the most-recent revision being the NCC 2022. Provided by Wikipedia
