Hi
I live in Adelaide too.
The WEA runs several photography courses;
all but one are booked out:
http://www.wea-sa.com.au/It depends what you want / need to learn, but there are lots of them available, including some on-line. I haven't tried so cannot comment. A friend is doing one through TAFE and loving it. Some websites are very useful. Try
http://www.slrphotographyguide.com/; http://www.bmpt1.com/#backtotop and
http://www.kenrockwell.com/index.htm. The latter one has lots of useful info. Some people 'knock' Ken Rockwell, but he has some useful stuff. Hope this helps.
In the meantime, what are your most important needs? What equipmnt do you have and what sort of photography are you interested in?
I really do recommend you use this site to read the comments / critiques of photographs submitted. Ask questions; you will find lots of people willing to help.
