If you are scheduling a call between San Francisco and Sydney, the overlap window is limited to typical business hours. When it is 4 pm in San Francisco it is 9 am in Sydney — a workable window for scheduling. The latest reasonable overlap is around 5 pm in San Francisco (10 am in Sydney). Outside this window there is effectively no good overlap for regular office hours.
Scheduling a family call between San Francisco and Sydney takes a little planning. San Francisco is 17 hours behind Sydney, which means there's no window that feels comfortable for everyone at the same time. The most manageable option is early evening in San Francisco — around 7 pm — which puts Sydney at 12 pm. Someone will need to stretch a little, but at least no one's setting a middle-of-the-night alarm. Weekends tend to give the most flexibility if you can agree on a time in advance.
