Apart from the "CDAS Family" of web sites, Facebook pages and forums, there's a wide world of Australian and international sites containing more than any of us could possibly know about the hobby.  Do remember that what is true in one place may not be in another - laws, the availability of particular species, climate and water parameters vary widely even within Australia.  Feel free to ask any questions via the forum or our Facebook Page if you are in doubt about anything you read online or just need some local knowledge.  You could also suggest a link.
