g'day

does anyone know of services/websites online that does flight tracking... worldwide or atleast europe. im trying to find something similar to melboure airports website which shows the location of any flights to and from melboune(give a basic graphical but live location of the subject flight). is there a programe or online service that does it?. I've searched the forum but ive got nothing but U.S based commercial flights only.

any suggestions on where one might find information
