The hard part is a female and male both doing this in a period they can viably reproduce and meeting eachother on the islands. I'd assume 100s of moose would need to attempt this before a population occurs.

It is a low probability of happening, but species spreading to a completely different part of the world from floating thousands of miles across an ocean and having a viable population in that new area also happened a lot more often than you'd probably think, so two moose swimming on their own 18 km is not too much of a stretch.

If a small population was already there, say, introduced by people, every moose that migrated there would be a breeding candidate.
