I love listening to Australian radio phone-in shows. If you log on during the day you are listening to the Aussies in the small hours. The majority of callers appear to be little old ladies who just want a chat, and lots of drunks, some of whom seem to be driving trucks across the Outback. But the best bit is that you can email the stations and get your message read back to you within minutes.
