As noted previously on this subject, there is no significant "daylight" to "save" for people north of the Tropic of Capricorn.
I've yet to see any DS advocates comment on how the so called "benefits" of DS are completely dependent on where you live. Perth people just see DS from the Perth-centric point of view with no regard for the effect on people in Kalgoorlie, Broome, and, most especially Kununnara. The latter location will have no DS effect at all even in the peak of summer, because on average, they recieve less than 1 hour of extra sunlight during the summer. Albany has some 90 minutes more daylight in December than Kununurra even though both have sunrise at the same time.
One solution might be to localise DS to south of a line between Geraldton and Esperance. Then the Perthlings would have their precious DS without affecting parts of the state where it made no sense, and everyone would live happily ever after

But that would spoil the game plan of DS pushers wanting to treat everyone in the state of WA as if we all lived in Perth.
