Rio de Janeiro is 12.5 hours behind Adelaide

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

Coordinating Adelaide and Rio de Janeiro is tricky: 12.5 hours of separation means their standard hours don't intersect. Async-first is your friend here. Reserve real-time meetings for the rare occasions someone can log on before or after hours. The window above shifts seasonally: Adelaide keeps daylight saving while Rio de Janeiro ignores it.
