Using Websites
There is a wide variety of information available on the Internet, some more reliable and applicable to academic studies than others. For example, using data from the Australian Bureau of Statistics may be highly relevant to some assignments, and is a reliable source. Some well-renowned scholars and Christian voices also host personal blogs to discuss their opinions, and these may also be reasonable to cite for assignments.
However, anyone can create a website and make it look official, so be careful with information found through a basic Google search.
