I know that daylight saving has genuine disadvantages for some people, however the argument about leaving time as nature intended and the argument about consistency are considerable weakened if you check sunrise and sunset times across WA.
This morning the sun rose at 5:35 in Esperance, 5:37 in Broome and 6:00 in Perth.
It will set at 5:52in Esperance, 5:48 in Broome and 6:16 in Perth.
Much greater inconsistency can be seen if you compare summer and winter in those places.
In Esperance, thesun rises as early as 4:38 and as late as 6:57.
In Broome, it varies from 5:12 to 6:21, and in Perth from 5:07 to 7:17.
Summer and winter sunset times for those same three locations show similar variation.
So depending on your location and the time of year, the sun in WA might rise anywhere between 4:38 and 7:17.
Those variations are greater than the one hour change involved in daylight saving.
Daylight saving doesn’t suit everyone and there are valid arguments against it, but the argument about consistency in not very convincing.
The data comes from this site.
