I don't think an anagram is indicated in this clue.
Rather it is one word (bus) written around another word (bali - "island resort") neither of which have been re-sorted.
I also think it would be quite unusual (and maybe a bit unfair)for the setter to indicate that the answer is an anagram of two words that aren't given.
For anybody interested the full clue was,
Hartebeest taken by public transport round island resort.
Answer:Bubalis
