You are required to make a legal deposit if you publish a work in Victoria.
The statutory obligation of legal deposit requires publishers to deposit copies of their publications in libraries in the country in which they are published. A copy of any work published in Australia must be deposited with the National Library of Australia and the Victorian State Library. Legal deposit of the material is the responsibility of the publisher or author.
Legal deposit extends not only to commercial publishers, but also to private individuals, clubs, churches, societies and other organisations. Legal deposit should not be confused with copyright - a protection granted automatically in Australia from the time a work is created.
Please consult the responsible agency for more information and to ascertain the level of compliance (if any) that may be required.
