I think there are situations that are not
rare and where voters will have a clear
incentive to vote strategically in IRV.
Here's one example from a one-dimensional
opinion space.

45: A>B>C
20: B>A>C
05: B>C>A
30: C>B>A

I think some of the C supporters should
vote B>C>A to guarantee (or increase the
probability) that B will win instead of
A.

I think the voters will have sufficient
information if there are few reasonably
reliable polls available shortly before
the election. The example could quite
well be from some real public election.
