Plotting aircraft on google maps - my site

Great job Geoff with your Flight Tracker, very impressive.

This may be a newbie question but does Flight Tracker monitor VFR aircraft positions. I am under the impression that these don't use squawk codes but are monitored by airport radar. I am in Sydney and I would like to watch helicopter movements as I am along a popular flight path.

Do you or others know how these are usually tracked?
