The initial compass bearing from Sydney to Singapore is 298° (WNW), so a great-circle flight path leaves Sydney heading roughly WNW. 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.
