go to timeanddate.com they have all the info you could want
type in "local time sydney" into yahoo search or obviously the city in australia you are interested in - and will give you the local time so you can compare to your own time
Remember that it's changing all the time. Since the two continents are in differenct hemisphers the difference is (normally) offset by two hours each time the two go into or emerge from daylight savings time. (one 'springs' forward as the other 'falls' back)

For example during part of the year the time difference between New York and Sydney is 16 hours, and the rest it's 14 hours (or 8 and 10 hours, depending on which direction you move around the globe).
