Here is some information on the origins of the Australian Legal System. This link also covers various other topics within the Australian Legal System such as 'Making Laws', 'Land and It's Uses', 'Environment and Planning' etc.

Quite interesting reading. There are so many and diverse legal systems around the world.
It will be interesting to compare and to research these further in regards to their origins and the influences these origins have had on the way they are structured today.
