For anyone genuinely interested in the subject matter at hand in an Australian context,
here is a good place to start. And
here of course.
Choose the area you want to know more about, click on the "in detail" tab and follow the references. A quick way to get to the main studies involved in each area. Follow the references in those studies to get across the various forms of source data from other research studies. Or if you like to sit down and read a book you can download
this. And follow the references again to the source data and research of whichever detailed element interests you. There are certainly plenty of them.
You can go as deep or as shallow as you like on each topic by going through the references. Contact information is also there for anyone with specific questions you want to ask but you will need to have specific questions on data sets etc - general questions will of course just earn you a hyperlink back to the website.
Have fun!
