Tasmania is now on summer time, but the ABC isn't retiming Radio
National and is just telling listeners there to tune in one hour
later.

Queensland isn't going on summer time but there are some people in the
"Gold Coast" area who would like to go on DST despite the policy of
the state government in Brisbane.

I'm not sure whether the RN stream comes from Sydney, NSW or
Melbourne, Vict. or Canberra, ACT but whatever it is the 5:30 A.M. old
Brit comedy slot is still on GMT+10.so apparently the most populous
section of Oz ain't on DST yet.
