Information:

International Access to Information Day is held on 28 September every year and recognises the community’s right to access government-held information.

The right to information is enshrined in access to information laws across Australia and New Zealand. We are among more than 120 nations around the world to guarantee citizens these rights — a significant expansion since 2009 when UNESCO recorded only 40 countries with these laws.

Australia’s Freedom of Information Act 1982 (FOI Act) recognises that the information government holds is a national resource and is managed for public purposes, and that public access to it should be prompt and at the lowest reasonable cost. The FOI Act applies to Australian Government ministers and most agencies, and other Australian states and territories have equivalent legislation.
