ComLaw, incorporating the Federal Register of Legislative Instruments (FRLI), is the legal information retrieval system owned by the Australian Attorney-General's Department.

As new, up-to-date compilations are added to ComLaw and the FRLI, the previous compilations are retained as Historical Data. If you want to see an item of legislation as it looked at a particular date, the historical data is the place to look. The historical data also includes legislation of the Commonwealth that is no longer in force.
