CSIRO did a study on it and said the effect was from longer summer days . The Daylight Saving is only a very small fraction of it. I forget the amount.

There isn't any extra daylight because of dayling savings.
Daylight savings just means your clocks are wound back an hour during certain months of the year.
You still have more sun in the summer and less sun in the winter months, but it's not because of daylight savings.

Daylight savings does not cause your curtains to fade, the sun does.

I was going to post a link to the song "I Hate Summer" by the Ken Noath Ockerstra.
Unfortunately I couldn't find one.

Instead I'll say that I think SA should eventually synchronise with Queensland.

The railway gauges were simpler.
Perth is 1 1/2 hour behind Adelaide which has DS + 1/2 hour.
So Bris is 1/2 hr behind Adelaide which is 1/2 hr behind Sydney.
Buy curtains in Sydney.
