Hello. I'm a student from Korea and I'm going to walk from Brisbane to Noosa as the title says with my friends during vacation. Is there a legal problem with this? I'm asking because I don't know about Australian law because I'm an international student.
Thank you
Legally you're probably fine as you can walk on the shoulder of roads in Australia. Realistically this is a very dangerous and unpleasant place to be with traffic travelling near to you at very high speed.
The bigger immediate issue is water: there are often no reliable sources for large stretches and it's very hot. Camping facilities are also set up for motorised travel and at a stretch cyclists.
The trip is possible, but if you're asking on Reddit for advice it's probably not going to go well.
