It's been on for a few years now.

Telstra turned it on when Sol arrived and discovered that it wasn't
on. It was pretty much his first order.

Some handsets implement their own Daylight Saving function, and have
it wrong now that those states who have daylight saving (except WA)
have moved the start / finish dates. The handsets attempt to be smart,
and make a mess of it.

Also, the time on the handset doesn't change at daylight saving change
until you power down / power up.

Good Luck.
