Singapore sits at 1.3521°N, 103.8198°E, while Sydney is located at 33.8688°S, 151.2093°E. The initial compass bearing from Singapore to Sydney is 133° (SE), so a great-circle flight path leaves Singapore heading roughly SE. 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 35.22° and the longitude difference is 47.39°. 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 Singapore and Sydney is approximately 17.6520°S, 125.1882°E. This is the great-circle halfway position — the spot where you would be exactly 3,153 km from each city.
