Incredible charts is Aussie only and provides a good forum for swapping notes as well as some excellent technical analysis summary info to help you learn more about this area.

Bigcharts provides you with UK and USA stocks as well as Australian stocks. I find their Java charting the most effective. To get an Aussie stock, type in the symbol as "au:stock ticker" - so for BHP it would be "au:bhp", for Telstra it would be "au:tls".
