Why people convert Perth to São Paulo time

Scheduling a call from Perth to São Paulo: a 10:00 AM start in Perth lands at 11:00 PM in São Paulo the previous day, so you can confirm the slot without doing the arithmetic yourself.
Handling a -11h gap: Perth and São Paulo have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in São Paulo is 10:00 PM in Perth.
Watching a live event or market open: Perth viewers need 10:00 PM in São Paulo to catch a 9:00 AM start there, and 11:00 AM if the event is anchored to Perth.

Always state the zone abbreviation, not just the hour. "3:00 PM AWST" is unambiguous; "3 PM" across a -11h gap is not.
With a -11h gap there is no shared 9-to-5 window, so alternate the early start: one week Perth takes the early slot, the next week São Paulo does.
