The Australian Building Codes Board (ABCB) is committed to ensuring practitioners of all experience levels can understand and apply the code. To support you in your job and education, we regularly produce resources such as news articles, videos, infographics and case studies.

You can search the resource library by the topic you’re interested in, your profession or by a specific resource name. Each of our sites has its own resource library which focuses on topics specific to that site. Hence, NCC-related material is collected in the NCC Resource Library and so forth. If there’s something specific you would like to see made into a resource, please get in touch.
