Best time to call between UTC and Sydney
Within normal office hours (09:00–18:00) in both cities: no overlap within 09:00–18:00; one side must take an early or late call. For a compromise outside that window, the fairest slots are the ones nearest each side's start or end of day, alternating who takes the inconvenient hour.
