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.
