Explanatory Memoranda (EM) are publications which accompany Commonwealth and State Bills. Their purpose is to explain the Bill, clause by clause, initially when it is debated in parliament. Subsequently they are useful for statutory interpretation.

Learn more about the history of EMs from this article 'Was There an EM?" from the Australian Parliamentary Library. 

Western Australia

• EMs were rarely published prior to 2000. They are now compulsory with all Bills. They are available for most Bills from 2000 onwards on the Bills tab on the Parliament of Western Australia website.
• If an EM is available it will be listed on the Bill homepage (click on the name of the Bill to see the Bill homepage)

Commonwealth

• Before 1982: use the Index to Explanatory Memoranda 1901-1982 on the Parliamentary Library webpage
• From 1982, the provision of EMs has been standard practice for Commonwealth Bills. Some of these may be available on the shelf in the Legislation collection on the top floor of the Beasley Law Library

In both State and Federal Parliament, Bills are considered by various Committees during their passage through Parliament.  In each House, a Committee of the Whole house (with members from a range of parties) considers the Bill and this is when amendments can be made.  This occurs after the Second Reading of the Bill.

Sometimes Bills are referred to special committees, such as Select Committees, Standing Committees or Legislation Committees. These Committees publish reports which can give researchers an insight into the background to a Bill, areas of debate or disagreement, and any policy issues that might arise. Committee Recommendations are not always adopted by the Government, but the Ministerial responses to recommendations are usually available with the Reports.
