The number of bills introduced, debated and passed by the Parliament during a sitting week can vary greatly. The number of bills passed by both houses of Parliament and signed into law by the Governor-General over the life of a parliament also varies.

The House of Representatives has put together an interesting table of statistics about this topic, dating back to 1901. You can find the table by following this link and clicking on ‘General statistics’. Using this table, you can see that the largest number of bills passed into law in one year is 264 (in 1992) and the smallest number of bills passed into law in one year is 12 (in 1907). The average number of laws made per year since 1901 is 108.

This table does not list how many bills have been presented to the Senate each year. You can find a record of all the bills passed by the Senate in each Parliament going back to the 31^{st} Parliament (1978-80) here.

Lots of other statistical information about the Parliament can be found at Parliament Now, Senate StatsNet and House of Representatives Statistics.
