NZ went on DST already Sept 29, of UT+13, as absurd as that may seem. This means any SW programming taken directly from RNZ National now appears one real UT hour earlier. This may also require juggling of some other programming and frequency usage.
DU uncoordinated as DST does not begin until Oct 6 in the parts of Australia observing it: SA, VIC, TAS and NSW.
(And did you know that there is a small enclave in the SE corner of WA, Eucla, with its own unique timezone of UT +8:45 but no DST?) Map:
That`s a compromise between WA +8:00 and adjacent SA +9:30 during standard time.
