There are no "north QLD diamond pythons", diamonds are predominantly from the south (NSW). Cloudy eyes mean she is going into shed again. Happens every 4-6 weeks for a young snake but the period is longer in older snakes. How old is she? If you have her old shed check the head piece of the skin and see if there are little clear scales where the eyes were. If not it may be retained shed but that's quite uncommon
