Well, I know that to fly from Germany(that's close to the Netherlands, where Stranger lives if I'm not mistaken) to Australia/NZ and back costs more than 5000EUR with BA or Lufthansa and I guess most other airlines as well. Visiting Kukri should cost about a fifth or so, if he offers you a bed you can even forget about a hotel.

Of course you can also acquire a paddle boat and travel to Australia using your muscles and a compass, that should be rather cheap, no need to work for long.
