Ok, my bad. I should have said Australia "spans" 3 time zones. In the East it is GMT+10, and the West is GMT+8

Thats just those areas aligning themselves with the most suitable time in their zone for sun up and sun down. And the 1st link you provided states 6 time zones. But thats just because of DST in use at the moment. That information will be wrong, (if its not updated) in another month or so....
