Malaysia to Papua New Guinea by motorcycle?

10 Is it possible to ride from Malaysia to Papua New Guinea by motorcycle. Any help would be much appreciated. transportation malaysia motorcycles papua-new-guinea share | improve this question edited Dec 12 '16 at 8:01 Mark Mayo ♦ 129k 76 569 1289 asked Dec 12 '16 at 7:26 Gareth Gareth 54 1 3 13 Um, no not unless your motorcycle flies. There's water in the way. – Roddy of the Frozen Peas Dec 12 '16 at 7:42 I presume the route is somehow Malaysia-East Timor-Darwin Australia and on.
