São Paulo is 12.5 hours behind Adelaide

There is no standard 8-to-6 overlap. Someone joins early or late.

Practically speaking, Adelaide and São Paulo never share office hours; 12.5 hours of separation keeps their days apart. To talk live, someone has to flex: an early start in São Paulo can catch the tail end of the day in Adelaide, or the other way round. Bear in mind Adelaide shifts for daylight saving while São Paulo stays fixed — recheck these hours after each clock change.
