Houston to Melbourne shipping route.

Houston to Melbourne is a 9,695 nautical mile shipping route via Panama Canal, heading south west from the United States to Australia. That is 17,955 km of water against 14,472 km as the crow flies. On the way the vessel passes Panama Canal, so canal transit fees and waiting time at the canal are part of every voyage.

Pure steaming time is 28.9 days at 14 knots. A carrier that slow steams at 12 knots to save fuel needs 33.7 days, and a fast 18 knot string about 22.4. Container transit time on a liner service is longer than the steaming time: ships call at other ports on the rotation, and cargo may transship at a hub. Add terminal time at Houston and Melbourne to plan the full ocean transit time.

The next option is via Cape of Good Hope, 13,342 nautical miles, 3,648 nm longer than the main route. Carriers pick it when Cape of Good Hope is congested or closed.

352 nm of the route, 4% of it, lies inside North American ECA. In an emission control area ships must burn fuel with no more than 0.1% sulphur or clean the exhaust with scrubbers. That fuel costs more, and carriers add it to the ocean freight bill as a low sulphur or ECA surcharge.

Container freight rates on Houston to Melbourne move with fuel prices, ship capacity and the season. Compare several carriers before booking: the cheapest sailing is often the slowest one. At Melbourne (AUMEL) carriers give about 8 free days before demurrage and detention charges start, so plan the truck or rail pickup before the box lands.

Of the 65 port to port routes from Houston in this directory, Melbourne is the 44th shortest. Closer destinations include Jebel Ali (9,663 nm), Karachi (9,589 nm) and Sydney (9,386 nm).
