Ipod touch 4g release date australia?

Harvey norman has already started selling them. When i was reading the paper of Friday it said "The new iPod touch, now available in limited quantities only at Bourke st, Nunawading, Knox etc:. Harvey Norman has started selling them but only the major stores are selling them, and they only had limited stock. Some places are getting some models earlier for others, for example, on Friday i went to see the new iPod touch at Harvey Norman but they didn't have the Nano because it hadn't arrived yet.
