Perth sits at 31.9505°S, 115.8605°E, while Sydney is located at 33.8688°S, 151.2093°E. The initial compass bearing from Perth to Sydney is 103° (ESE), so a great-circle flight path leaves Perth heading roughly ESE. 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 1.92° and the longitude difference is 35.35°. 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 Perth and Sydney is approximately 34.1853°S, 133.3371°E. This is the great-circle halfway position — the spot where you would be exactly 1,646 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.
Sydney is roughly 2 hours ahead of Perth. When it is 09:00 in Perth, it is approximately 11:00 in Sydney. A 2-hour shift is small enough that most travelers adjust within a day. Daylight saving time can shift the offset by an hour during certain months, so confirm the exact difference for your specific travel dates.
