I have just come across a website linked to the Bureau of Meteorology's webpage called "Indigenous Weather Knowledge". It sounded very intriguing. The link is: http://www.bom.gov.au/iwk/
It appears only to have information for the Northern Territory at the moment. I don't know whether there will be additional information posted for the rest of the country at a future time, but certainly something to look into, as I haven't really even thought about this previously...well, not under the title of "weather knowledge".
