Apparently not all repositionings of cruise ships are cruises and not all repositioning cruises are at budget travel prices, by which I mean a comparable price to a flight on a LCC airline.
But I would love to know if there is any repo cruise in this kind of budget range from SE or E Asia to Australia in 2017?
I believe there's no centralized place to look for these and that not all such cruises that might fit this question are even necessarily labelled as repo cruises.
This is a new kind of travel to me I just heard of the other day. If it's also new to you please see the previous, introductory, question on the topic here.
