Being that TradingRoom closed, Quotetracker will not work anymore (Plus QuoteTracker is unsupported itself now). Medved Trader http://www.medvedtrader.com (from the original developers of QuoteTracker) works with various Australian sources. For free delayed, you can use Yahoo. For real-time data, MT can get data from Commsec, E*Trade, Interactve Brokers, Bell Direct. Backfill sources vary - Commsec backfill support was added in the latest beta.
