The sea route from Jeddah (Saudi Arabia) to Sydney (Australia) is about 7,635 nautical miles, which is 14,140 km or 8,786 statute miles. The route transits Bab-el-Mandeb. That is about 6% longer than the direct great-circle line, because the practical route follows coastlines and shipping lanes.
Voyage time by boat speed
Time underway is distance divided by speed. These are continuous-passage figures with no stops or weather margin.
| Boat and speed | Time underway |
|---|---|
| Sailboat, conservative (5 kn) | 63d 15h |
| Sailboat, average (6 kn) | 53d 1h |
| Displacement trawler (8 kn) | 39d 18h |
| Fast trawler (10 kn) | 31d 20h |
| Planing motor yacht (15 kn) | 21d 5h |
| Fast motor yacht (20 kn) | 15d 22h |
Planning estimate, not navigation
This distance is computed over the open Eurostat shipping-lane network. It is a realistic passage length for planning, but your sailed distance will differ with weather routing, currents, draft, and the exact berths you leave from and arrive at. Always verify against official charts.

How far is Sydney from Jeddah by sea?
About 7,635 nautical miles (14,140 km / 8,786 statute miles) along the practical sea route, which transits Bab-el-Mandeb. The straight-line distance is shorter, but boats follow coastlines, channels, and traffic lanes.
How long does it take to sail from Jeddah to Sydney?
At a typical sailing average of 6 knots it is about 53d 1h underway. A 10-knot trawler needs about 31d 20h, and a 20-knot motor yacht about 15d 22h. Add margin for weather, currents, and stops.
How is this distance calculated?
It is computed over the open Eurostat global shipping-lane network, the same kind of network freight routing tools use. It is a realistic planning estimate, not a navigation product: your sailed distance will vary with weather routing, draft, and the exact harbors you use.
