Matt,
The main difference is not between states east/west of each other (NT and
WA), but between north and south. The Northern Territory top end and
northern Western Australia (Kimberlies, Pilbara, etc...) have a much
smaller difference in daylight hours (being between paralels 10 and 20
south) than southern WA (~35 deg. S) or Tasmania (~40 deg. S)
Here at 42 deg S, we have 15 h long summer days and conversely 15 hour long
winter nights.
