[Enchilada]

Dealing with wild and crazy Queenslanders is one thing, but the lack of understanding of the necessity of daylight savings throughout Australia and the rest of the world still amazes me in the total reckless abandonment of common sense.
Daylight savings is dependant only on THREE main factors. It is firstly mainly caused by the difference between in latitudes - namely, the further south you go the larger the time variances between daylight hours in summer and winter AND that the Earth's axis is tilted at 23.5-odd degrees to the ecliptic. So the length of daylight hours between sunrise and sunset OR night-time hours sunset to sunrise varies only on the apparent declination of the sun. If this were the only variable, daylight savings would not be necessary. However, the other third factor making this more complicated is that the Earth's orbit in not circular but slightly elliptical, causing the times of sunset and sunrise to be increase or decrease up to as much as about 15 minutes earlier or later (as seen in the yearly analemma).
So the closer to the equator the difference is not as significant as those living further south.
In the end it is NOT a kind of blatant latitude discrimination of people. It is a compromise on the mean latitude to make the daylight hours more useful for daily human eight hour work-play-sleep cycle. (We are habitual creatures based mostly on the sun for activity) Furthermore daylight saving is synced mostly to MORNING when the daily circadian rhythms when the electrical activity rises close to sunrise - when our bodies physically anticipating the new day. Its aimed to match human activity so it starts around 6pm every day of the year.
Now most Queenslanders don't want daylight savings while most Tasmanians what more daylight saving - so most Governments just decided on a compromise one hour should satisfy everyone.
So if you must blame something, curse the fact that the Earth is round, it is tilted on its axis, and our orbit in our solar system is elliptical! (Else try to get Government change it to eliminate all the complicated caused of the differences. I.e. planetary engineering.)
Stop wanting to blaming every authority under the sun because someone wants to maintain a delusion that we are messing with nature! Daylight savings is merely a compromise to maintain some normality in our daily lives - so it matches the seasons.

** There is also a significant difference in longitude within time zones, but to keep it simple I have alone brought up this for a given location.
