It's actually central time (i.e. South Australia and the Northern
Territory) that's +0930 (standard; +1030 daylight savings in SA only).
Western Australia is +0800, the same as China.

The logic involved is much the same as with having +0900, except that
you're half an hour ahead of +0900, so you go +0930. Some areas do
offsets of a quarter of an hour too, as with the defacto +0845 I
mentioned before in eastern Western Australia.
