Best overlap: 8:00 AM to 10:00 AM in Milan is 4:00 PM to 6:00 PM in Brisbane.
If you set up a recurring sync, 8:00 AM to 10:00 AM in Milan (4:00 PM to 6:00 PM in Brisbane) is the natural home for it. With overlap this short — around 2 hours — a recurring slot at 8:00 AM in Milan (4:00 PM in Brisbane) is worth its weight in gold. Finally, Milan observes daylight saving and Brisbane doesn't, so this window shifts by an hour for part of the year — recheck it each spring and autumn.
