Business Hours Overlap: Istanbul Morning Meets Sydney Afternoon
The only practical overlap for real-time work is Istanbul's morning against Sydney's afternoon.

Travel Time and Jet Lag: Istanbul to Sydney
A direct flight from Istanbul to Sydney takes roughly 16 to 17 hours. The time zone shift hits harder than the flight duration. Flying east, you lose 7 to 8 hours.
Leave Istanbul at 14:00 and you land in Sydney around 09:00 the next day. Your body clock reads 01:00 or 02:00 Istanbul time. Eastbound jet lag is more severe because you shorten your day. Allow 3 to 5 days to adjust.
Flying west from Sydney to Istanbul, you gain 7 to 8 hours. Depart Sydney at 10:00 and arrive in Istanbul around 18:00 the same day. Your body thinks it is much later. Stay awake until local night to reset.
