JNB-bound flights are the slower direction by about 135 minutes in our estimate: the route runs mostly east–west through latitudes where the prevailing westerly winds at cruise height are strong, so heading east rides a tailwind and heading west fights a headwind. How we estimate it.

Time zones and jet lag

JNBAfrica/Johannesburg — UTC+2 now; UTC+2 all year (no daylight saving time)
SYDAustralia/Sydney — UTC+11 now; UTC+10 standard time, UTC+11 during daylight saving time
DifferenceSydney is 9 hours ahead of Johannesburg today; +9 h in January and +8 h in July because daylight saving time starts and ends on different dates (or not at all).

Jet lag, flying JNB → SYD. Your body clock has to move 9 hours earlier, like an eastward trip. A common rule of thumb is that the body clock adjusts by roughly one time zone a day, so expect up to about 9 days to fully adjust. Shifting earlier (as here) is usually the harder direction; morning daylight at the destination helps. Flying the other way, the shift is reversed.
