I can recommend the following books on Parliament in general, the Australian Parliament in particular, and politics in general.
I personally own, have read, or am familiar with all of them. The clickable link enables immediate purchase from Amazon Books. Many books are also available secondhand at a reduced price.
Amazon Books is highly recommended. Purchases of any kind from Amazon made through clickable links assist in the financial running of this site, so even if you’re looking for something completely unrelated to politics you will assist the site to remain free by following these links.
