Sydney sits at 33.8688°S, 151.2093°E, while Bangkok is located at 13.7563°N, 100.5018°E. The initial compass bearing from Sydney to Bangkok is 306° (NW), so a great-circle flight path leaves Sydney heading roughly NW. Because the Earth is curved, the actual heading shifts gradually along the route — pilots and navigation systems update it continuously instead of holding a single fixed compass bearing.
The latitude difference is 47.63° and the longitude difference is 50.71°. Each degree of latitude represents about 111 km, which is one reason cross-latitude routes feel longer even when the map looks similar to east–west journeys.
The geographic midpoint between Sydney and Bangkok is approximately 11.0953°S, 123.7317°E. This is the great-circle halfway position — the spot where you would be exactly 3,768 km from each city. On long-haul flights this point usually falls over open ocean or remote terrain, which is why in-flight maps often look "empty" mid-route.
