Hi Craig,
to IceInSpace!
I'm glad you found your way here from the article in the paper.
I listen to loads of astronomy podcasts as well. The only southern-hemisphere based one I know of, is "ABC StarStuff" - head to the ABC website and search for it.
I usually listen to Astronomy Cast, Star Stuff, Science@NASA, This Week @ NASA, Dr Karl's Greatest Moments in Science, and Astronomy 161/162. Occassionally i'll listen to a few others but they're my staple diet
also to undeadspirit! Don't be shy in creating new threads in the relevant sub-forum to ask any specific questions. This thread is so long and so full of introductions that often specific questions can get lost.
