I want to get a flight to AUS - NZ - Singapore, then try to explore as much of Asia as possible without buying a plane ticket. Once your in Singapore could you travel on land through all of Asia (China, Hong Kong, Indonesia, Bali, Malaysia, etc?) without it being ridiculously difficult? Nightbuses, boats, trains, whatever! Ultimately Id like to end up in India - Nepal - Tibet and then get a plane ticket home from there. Whwere is feasible to travel on ground once your on the Asia mainland and what kind of costs are we looking at? How difficult could it be regarding VISA restrictions if I dont have my outward ticket?
