Neither route is practical by car. Flying is the recommended transport for both.
Dubai (United Arab Emirates) has a population of 3,331,420 and is located in the Dubai region of Asia. It's a significant city with good transport links and cultural offerings.
Singapore (Singapore) has a population of 5,850,342 and is situated in Singapore, Asia. This major global city has multiple airports and world-class infrastructure.
Choose this route if your priority is reaching Dubai (United Arab Emirates) — a city of 3,331,420 in the Dubai region of Asia. Despite being the longer of the two at 12,050 km, it makes sense when Dubai itself is the destination, the schedule fits better, or ticket prices are noticeably lower. This is a fly-only route in practice — overland travel is not realistic at 12,050 km. The initial bearing is 289° (WNW), so a great-circle flight leaves Sydney heading roughly WNW.
This route is the right call if you are heading to Singapore (Singapore) — a city of 5,850,342 in the Singapore region of Asia. It is also the shorter of the two at 6,306 km, saving about 7h 11min of flying and around 1,465 kg of CO₂ per passenger. Overland travel is not practical for 6,306 km; flying is the realistic mode. Departing Sydney, the great-circle bearing toward Singapore is 298° (WNW).
Sydney (-33.87°, 151.21°) and Dubai (25.20°, 55.27°) sit with a time-zone shift of -6 hours. Sydney (-33.87°, 151.21°) and Singapore (1.35°, 103.82°) have a -3-hour offset. Routes with time-zone shifts of 5 hours or more typically produce noticeable jet lag — plan one recovery day per three time zones crossed.
Singapore is closer at 6,306 km, which is 5,744 km (48%) shorter.
12,050 km (7,488 miles). Flight: ~15h 34min.

All distances on SnapDistance are calculated using the Haversine formula, which determines the great-circle distance between two points on Earth's surface. This gives the shortest possible distance over the globe, which is the measurement used for aviation and navigation. Actual travel distances by road or rail are typically 20-40% longer due to terrain, borders, and infrastructure routing. Flight times assume 800 km/h cruising speed with 30 minutes for takeoff and landing. Driving estimates use 80 km/h average speed with a 30% road distance factor.
