> The thing about this is that if Perth's time zone ever changes so erratically or with such little notice that participants need to be notified that the point-in-time of an upcoming meeting has changed

"erratically" and "with little notice" are pretty relative when it comes to timezone shifts. DST decisions have been made with as little as a week lead time, Samoa dropping an entire day off of its calendar was done with under a year lead time (noises started about 9 months prior, the act was assented 6 months prior).

> would we expect all athletes, organizers, fans, etc. to show up and do everything 1 hour earlier (by solar time)?

Usually yes.
