8. Tracking changes


It can be valuable to understand how an Act has changed over time. Most Acts indicate these changes using a system of abbreviations.

Abbreviation Meaning
ad  added
amd (or am)  amended
ins inserted
om omitted
renum renumbered
rep repealed

How to track changes

Traditionally, these abbreviations have been used to indicate changes to an Act in the Endnotes or Notes section found at the back of the Act. For Commonwealth Acts, for instance, you can turn to the Endnotes 4 — Amendment history.

The Amendment history for Section 69P of the Family Law Act 1975 (Cth) is:

s69P......................ad. No. 167, 1995; am. No 98, 2005.

This information would tell you that:

  • Section 69P was added in 1995 and amended in 2005
  • The Act number and year of assent of the amending legislation.

For a fuller picture of the amendments, you would need to find the amending Act (Family Law Amendment Act 2005 No. 98, 2005) using the information provided.

Some websites incorporate the amendment information in a more accessible way. For instance, the Queensland legislation website allows users who Turn history notes on to see the amendment history while viewing the Act.
