Honolulu sits at 21.3069°N, 157.8583°W, while Sydney is located at 33.8688°S, 151.2093°E. The initial compass bearing from Honolulu to Sydney is 222° (SW), so a great-circle flight path leaves Honolulu heading roughly SW. 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 55.18° and the longitude difference is 309.07°. 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 Honolulu and Sydney is approximately 6.9480°S, 178.2444°E. This is the great-circle halfway position — the spot where you would be exactly 4,083 km from each city.
