Library collection is not only a record of the development of human society, but also the basis of all library activities. The construction of library collection resources is an important symbol to measure the development level of libraries. Australia has only been founded for more than 200 years 1788, and the state attaches great importance to the collection and preservation of cultural resources. According to the provisions of the Australian Library Law, public libraries at all levels must develop their collections according to their own nature, tasks and directions. Each library will formulate collection development policies in different periods and plan the collection system accordingly. The National Library is responsible for preserving domestic documents. As the institution that keeps and collects all publications in Australia, it has the right to accept copies submitted. All printed documents, miniature documents and electronic documents published in China can be delivered. The collection focuses on politics, society, culture, economy and documents related to high-tech development. All state libraries in Australia are cultural resource centers in the state, and one of their duties is to collect and preserve local cultural resources in the state. In addition to various publications published in the state, they also pay great attention to collecting various local documents related to the state, which are of great research reference value. Victoria Library officially opened to the public on 1856. After a century and a half of development, its collection system has gradually improved. It not only completely preserves the historical and cultural heritage of Victoria, but also has distinctive local collection characteristics, prominent focus, distinctive features, diverse forms and high historical value. At the same time, the collection scope is very wide, and the collection variety is very rich, which is a profound knowledge treasure house dedicated to readers. This is largely due to the provisions of the deposit system in the Victoria Library Law 1988. At present, the library has more than 2 million books and/kloc-0,000,000 other documents such as pictures, maps and manuscripts. In their view, the library seems to be able to collect all the cultural resources, such as various performances, trademarks, posters, files, etc., and also specially collect many valuable and distinctive documents, such as art collections, children's documents, chess documents, maps and so on. Victoria Library has also taken different measures to strengthen and protect different types of documents in different periods. In addition, the museum has more than 3,500 precious historical relics. These collections will attract more and more attention over time, and the collection value will gradually increase. Local libraries pay more attention to practicality, popularity and popularization in literature collection, and the renewal rate and elimination rate of collected materials are relatively high. Except for local historical materials, all collections are mainly used to make them fully circulated and utilized, thus forming a complementary collection with the state library. The author finds that both the National Library and the State Library attach great importance to the collection of newspapers, including not only printed newspapers, but also micro-replication and CD-ROM databases. Newspapers and periodicals account for a considerable proportion in the total stacks, and many people are looking for them. Obviously, the newspaper utilization rate in Australia is very high.

The National Library is the national document cataloging network center of Australia, and its database system "Kinetica" (which was completely updated and renamed as Libraries Australia the day after we left the National Library, namely 12, 2005) connected more than 100 domestic 1000 libraries, thus avoiding the trouble of repeated cataloging in various libraries and truly realizing cataloging in Australia. This system is also a tool for interlibrary loan between Australian libraries. Libraries use this network to search, query and transmit demand information, which ensures the efficient development of national resource sharing.
