Meeting window
Working days of 9 AM to 5 PM do not overlap. The least disruptive slot is around 4:30 PM EDT, which is 6:30 AM (next day) AEST while EDT and AEST apply.
Daylight saving
Both zones change their clocks, on the dates listed below, so the gap can shift during the year.

The same conversion works for every city on these clocks, such as New York to Australia, New York to Sydney and Toronto to Australia.
